英文原文computer virusWith the computer in all areas of social life, the extensive use of computer virus attacks and prevention techniques are expanding. According to reports, the world suffer from computer virus infections and attacks of hundreds of millions of events, which seriously interferes with the normal life of human society, to the computer networks and systems have brought tremendous potential threats and destruction. At the same time, the virus also in the field of war, widely used in the Gulf War, the recent Kosovo war, both sides have used computer viruses to attack enemy, destroy the opponent's computer networks and weapons control systems, to a certain political objectives and military objectives. Can be expected, with the computer, the growing popularity of Internet use, in-depth to prevent computer viruses will be more and more national attention.A computer virus is a group by copying itself to infect other software programs. When the program runs, the embedded virus also will be run and infect other programs. Some viruses do not attack with a malicious code, but more carriers of the virus carrying code, if it is pre-configured environment for excitation, to infection and destruction. Maurice compiled from 80 of the first "worm" virus program so far, the world has appeared in many different types of viruses.It has long been the main goal of computer design is the pursuit of improved information processing capabilities and lower production costs, and inadequate attention to security problems are. The various components of a computer system, interface interface, conversion between various levels, there are many loopholes and weak links. Hardware designeven consider the lack of overall security, software, there are also more risks and potential threats. Testing of computer systems, the current lack of automated software testing tools and a complete inspection means, the vulnerability of computer systems for the generation and dissemination of computer viruses provides an opportunity; the global World Wide Web (www) so that the "Earth Village "and the implementation of the computer virus to create a space; new computer technology [/ url] in the continuous application of electronic systems for the realization of computer viruses, the objective conditions. Experts believe that the distributed data processing, re-programming embedded computers, network communications, computer standardization, software standardization, the standard message format, a standard data link, have made it possible for computer viruses. Implementation of computer virus's core technology is an effective solution injected into the virus. Which targets a variety of other systems, and from the computer host to a variety of sensors, bridges, etc., so that their computers are at a critical time trick or collapse, can not play a role. Current research from the foreign point of view, the virus injection methods are the following:1. Radio mode. Mainly through the radio transmitting the signature to the other electronic systems. This approach is the best way into the computer virus, while technical difficulties are greatest. Possible ways are: ① the other electronic systems directly to the radio receiver or transmitter device, so the receiver to process it and spread the virus to the target. ② posing as legitimate wireless transmission of data. Obtained or used according to standard protocols and data formats of radio transmission, emission pattern, to enable lawful transmission signal mixed into the receiver, and then enter the information network.③ looking for other information systems to protect the worst place to put the virus injection. Unprotected by the other data link will transmitthe virus to be protected or the target of the link.2. "Cure" approach. That the virus prior to the hardware store (such as chips) and software, then the hardware and software, directly or indirectly delivered to each other, so that the virus directly transmitted to the other electronic system to activate when needed to achieve the attack purpose. This attack is very subtle, even if the chip or component is thoroughly checked, it is difficult to ensure there are no other special features. At present, many computer components dependent on imports, the storm of this, the chip is vulnerable to attack.3. Backdoor attacks. Back door, a computer security system in a small hole, or maintenance by the software designers invented to allow people who know of its existence to bypass normal security measures into the system. Attacks in the form of back door there are many kinds, such as electromagnetic pulse can control the virus into the target system. Computer intruders often carried out through the back door attacks, such as the current widespread use of WINDOWS98, there is such a back door.4. Data control chain invasive. With the wide application of Internet technology to make computer viruses through the chain of computer systems, data control invasive as possible. Modification technique using the remote, you can easily change the data in the normal path of the control chain.In addition to these methods, but also through other ways into the virus.Because computer viruses are likely to cause great losses to users, people began to try every means to carry out preventive measures. Approximate methods are the following:1. Establishment of an effective computer virus protection system. Effective computer virus protection system should include multiple protection layers. One is access control layer; second layer of virus detection; third virus containing layer; Fourth, virus removal layer;Fifth, system recovery layer; six layers of contingency plans. The six computer protection system, there must be effective support for hardware and software technologies, such as safety design and standard operation.2. To prevent electromagnetic radiation and electromagnetic leakage. Electromagnetic shielding methods to block the electromagnetic radiation, so that can not only achieve the purpose of preventing leakage of computer information, and can prevent the "electromagnetic radiation type" virus attacks.3. Strengthen the building of a computer emergency response unit. Automated system should be set up security support unit to address issues related to the computer defensive.Computer virus attack and defense is evolving, to stay ahead of the computer virus against the position, must be based on trends, to implement key techniques in the follow-up study. Implementation of the follow-up study should focus on the following aspects: First, the model of computer viruses. Second, computer virus injection method, focused on "curing" stimulate the virus. Third, computer virus attacks, wireless networks focus on the standardization of data transfer and its security vulnerability and high-frequency electromagnetic pulse virus human virus, the effectiveness of the gun home. Fourth, studies dealing with computer viruses, security policy and defense technologies.中文翻译计算机病毒随着计算机在社会生活各个领域的广泛运用，计算机病毒攻击与防范技术也在不断拓展。
计算机病毒英文小论文Computer Virus
Computer VirusWith the rapid development of information technology , computer virus is becoming another security threat in our life.Computer virus is a program written by the people which can damage your computer system when the computer is running. It can't exist independently, it's always hidden in other executable programs, it's destructive, infectious and latent. When your computer is infected by the virus, it will make the machine work abnormally or cause your computer to crash.Now, I'm gonna talking some characteristics of the virus.First of all, it's parasitic, it's hidden in some programs, when the program is running, the virus will begin to destroy your PC; Second, it's infectious, it can be copied and spread to other computers swiftly; Third, it's latent, you can hardly find it out when the parasitic program isn't running; Fourth, it's invisibility, you can't find it out by yourself, you just can find it out by using anti-virus software.All these above are the characteristics of computer virus.How to prevent the virus and keep your PC safe is very important.First, you should strengthen your awareness, if you want to use the USB flash disk to copy something, you should scan the USB flash disk by anti-virus software to make sure it's safe;Then, when you surf the web, you must pay more attention to make sure the website is safe and legal. Finally, develop a good habit to scan your computer regularly is very necessary.。
计算机病毒(中英文对照)
计算机病毒A computer virus is a computer program that can replicate itself[1] and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability.Malware includes computer viruses, computer worms, Trojan horses, most rootkits, spyware, dishonest adware and other malicious or unwanted software, including true viruses. Viruses are sometimes confused with worms and Trojan horses, which are technically different. A worm can exploit security vulnerabilities to spread itself automatically to other computers through networks, while a Trojan horse is a program that appears harmless but hides malicious functions. Worms and Trojan horses, like viruses, may harm a computer system's data or performance. Some viruses and other malware have symptoms noticeable to the computer user, but many are surreptitious or simply do nothing to call attention to themselves. Some viruses do nothing beyond reproducing themselves.Virus programsThe Creeper virus was first detected on ARPANET, the forerunner of the Internet, in the early 1970s.[10] Creeper was an experimental self-replicating program written by Bob Thomasat BBN Technologies in 1971.[11] Creeper used the ARPANET to infectDEC PDP-10 computers running the TENEX operating system.[12] Creeper gained access via the ARPANET and copied itself to the remote system where the message, "I'm the creeper, catch me if you can!" was displayed. The Reaper program was created to delete Creeper.[13]A program called "Elk Cloner" was the first personal computer virus to appear "in the wild"—that is, outside the single computer or lab where it was created.[14] Written in 1981by Richard Skrenta, it attached itself to the Apple DOS 3.3 operating system and spreadvia floppy disk.[14][15] This virus, created as a practical joke when Skrenta was still in high school, was injected in a game on a floppy disk. On its 50th use the Elk Cloner virus would be activated, infecting the personal computer and displaying a short poem beginning "Elk Cloner: The program with a personality."The first IBM PC virus in the wild was a boot sector virus dubbed (c)Brain,[16] created in 1986 by the Farooq Alvi Brothers in Lahore, Pakistan, reportedly to deter piracy of the software they had written.[17]Before computer networks became widespread, most viruses spread on removable media, particularly floppy disks. In the early days of the personal computer, many users regularly exchanged information and programs on floppies. Some viruses spread by infecting programs stored on these disks, while others installed themselves into the disk boot sector, ensuring that they would be run when the user booted the computer from the disk, usually inadvertently. Personal computers of the era would attempt to boot first from a floppy if one had been left in the drive. Until floppy disks fell out of use, this was the most successful infection strategy and boot sector viruses were the most common in the wild for many years.Traditional computer viruses emerged in the 1980s, driven by the spread of personal computers and the resultant increase in BBS, modem use, and software sharing. Bulletinboard–driven software sharing contributed directly to the spread of Trojan horse programs, and viruses were written to infect popularly traded software. Shareware and bootleg software were equally common vectors for viruses on BBSs.[citation needed] Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by other computers.[18]Macro viruses have become common since the mid-1990s. Most of these viruses are written in the scripting languages for Microsoft programs such as Word and Excel and spread throughout Microsoft Office by infecting documents and spreadsheets. Since Word and Excel were also available for Mac OS, most could also spread to Macintosh computers. Although most of these viruses did not have the ability to send infected email messages, those viruses which did take advantage of the Microsoft Outlook COM interface.[citation needed]Some old versions of Microsoft Word allow macros to replicate themselves with additional blank lines. If two macro viruses simultaneously infect a document, the combination of the two, if also self-replicating, can appear as a "mating" of the two and would likely be detected as a virus unique from the "parents".[19]A virus may also send a web address link as an instant message to all the contacts on an infected machine. If the recipient, thinking the link is from a friend (a trusted source) follows the link to the website, the virus hosted at the site may be able to infect this new computer and continue propagating.Viruses that spread using cross-site scripting were first reported in 2002,[20] and were academically demonstrated in 2005.[21] There have been multiple instances of the cross-site scripting viruses in the wild, exploiting websites such as MySpace and Yahoo!. Nonresident virusesNonresident viruses can be thought of as consisting of a finder module and a replication module. The finder module is responsible for finding new files to infect. For each new executable file the finder module encounters, it calls the replication module to infect that file. Resident virusesResident viruses contain a replication module that is similar to the one that is employed by nonresident viruses. This module, however, is not called by a finder module. The virus loads the replication module into memory when it is executed instead and ensures that this module is executed each time the operating system is called to perform a certain operation. The replication module can be called, for example, each time the operating system executes a file. In this case the virus infects every suitable program that is executed on the computer.Resident viruses are sometimes subdivided into a category of fast infectors and a categoryof slow infectors. Fast infectors are designed to infect as many files as possible. A fast infector, for instance, can infect every potential host file that is accessed. This poses a special problem when using anti-virus software, since a virus scanner will access every potential host file on a computer when it performs a system-wide scan. If the virus scanner fails to notice that such a virus is present in memory the virus can "piggy-back" on the virus scanner and in this way infect all files that are scanned. Fast infectors rely on their fast infection rate to spread. The disadvantage of this method is that infecting many files may make detection more likely,because the virus may slow down a computer or perform many suspicious actions that can be noticed by anti-virus software. Slow infectors, on the other hand, are designed to infect hosts infrequently. Some slow infectors, for instance, only infect files when they are copied. Slow infectors are designed to avoid detection by limiting their actions: they are less likely to slow down a computer noticeably and will, at most, infrequently trigger anti-virus software that detects suspicious behavior by programs. The slow infector approach, however, does not seem very successful.In order to avoid detection by users, some viruses employ different kinds of deception. Some old viruses, especially on the MS-DOS platform, make sure that the "last modified" date of a host file stays the same when the file is infected by the virus. This approach does not fool antivirus software, however, especially those which maintain and date cyclic redundancy checks on file changes.Some viruses can infect files without increasing their sizes or damaging the files. They accomplish this by overwriting unused areas of executable files. These are called cavity viruses. For example, the CIH virus, or Chernobyl Virus, infects Portable Executable files. Because those files have many empty gaps, the virus, which was 1 KB in length, did not add to the size of the file.Some viruses try to avoid detection by killing the tasks associated with antivirus software before it can detect them.As computers and operating systems grow larger and more complex, old hiding techniques need to be updated or replaced. Defending a computer against viruses may demand that a file system migrate towards detailed and explicit permission for every kind of file access. StealthRead request interceptsWhile some antivirus software employ various techniques to counter stealth mechanisms, once the infection occurs any recourse to clean the system is unreliable. In Microsoft Windows operating systems, the NTFS file system is proprietary. Direct access to files without using the Windows OS is undocumented. This leaves antivirus software little alternative but to send a read request to Windows OS files that handle such requests. Some viruses trick antivirus software by intercepting its requests to the OS. A virus can hide itself by intercepting the request to read the infected file, handling the request itself, and return an uninfected version of the file to the antivirus software. The interception can occur by code injection of the actual operating system files that would handle the read request. Thus, an antivirus software attempting to detect the virus will either not be given permission to read the infected file, or, the read request will be served with the uninfected version of the same file.File hashes stored in Windows, to identify altered Windows files, can be overwritten so that the System File Checker will report that system files are originals.The only reliable method to avoid stealth is to boot from a medium that is known to be clean. Security software can then be used to check the dormant operating system files. Most securitysoftware relies on virus signatures or they employ heuristics, instead of also using a database of file hashes for Windows OS files. Using file hashes to scan for altered files would guarantee removing an infection. The security software can identify the altered files, and request Windows installation media to replace them with authentic versions.Self-modificationMost modern antivirus programs try to find virus-patterns inside ordinary programs by scanning them for so-called virus signatures. Unfortunately, the term is misleading, in that viruses do not possess unique signatures in the way that human beings do. Such a virus signature is merely a sequence of bytes that an antivirus program looks for because it is known to be part of the virus. A better term would be "search strings". Different antivirus programs will employ different search strings, and indeed different search methods, when identifying viruses. If a virus scanner finds such a pattern in a file, it will perform other checks to make sure that it has found the virus, and not merely a coincidental sequence in an innocent file, before it notifies the user that the file is infected. The user can then delete, or (in some cases) "clean" or "heal" the infected file. Some viruses employ techniques that make detection by means of signatures difficult but probably not impossible. These viruses modify their code on each infection. That is, each infected file contains a different variant of the virus.Encryption with a variable keyA more advanced method is the use of simple encryption to encipher the virus. In this case, the virus consists of a small decrypting module and an encrypted copy of the virus code. If the virus is encrypted with a different key for each infected file, the only part of the virus that remains constant is the decrypting module, which would (for example) be appended to the end. In this case, a virus scanner cannot directly detect the virus using signatures, but it can still detect the decrypting module, which still makes indirect detection of the virus possible. Since these would be symmetric keys, stored on the infected host, it is in fact entirely possible to decrypt the final virus, but this is probably not required, since self-modifying code is such a rarity that it may be reason for virus scanners to at least flag the file as suspicious.An old, but compact, encryption involves XORing each byte in a virus with a constant, so that the exclusive-or operation had only to be repeated for decryption. It is suspicious for a code to modify itself, so the code to do the encryption/decryption may be part of the signature in many virus definitions.Polymorphic codePolymorphic code was the first technique that posed a serious threat to virus scanners. Just like regular encrypted viruses, a polymorphic virus infects files with an encrypted copy of itself, which is decoded by a decryption module. In the case of polymorphic viruses, however, this decryption module is also modified on each infection. A well-written polymorphic virus therefore has no parts which remain identical between infections, making it very difficult to detect directly using signatures. Antivirus software can detect it by decrypting the viruses using an emulator, or by statistical pattern analysis of the encrypted virus body. To enable polymorphic code, the virus has to have a polymorphic engine (also called mutating engine or mutation engine) somewhere in its encrypted body. See polymorphic code for technical detail on how such engines operate.[22]Some viruses employ polymorphic code in a way that constrains the mutation rate of the virus significantly. For example, a virus can be programmed to mutate only slightly over time, or it can be programmed to refrain from mutating when it infects a file on a computer that already contains copies of the virus. The advantage of using such slow polymorphic code is that it makes it more difficult for antivirus professionals to obtain representative samples of the virus, because bait files that are infected in one run will typically contain identical or similar samples of the virus. This will make it more likely that the detection by the virus scanner will be unreliable, and that some instances of the virus may be able to avoid detection.Metamorphic codeTo avoid being detected by emulation, some viruses rewrite themselves completely each time they are to infect new executables. Viruses that utilize this technique are said tobe metamorphic. To enable metamorphism, a metamorphic engine is needed. A metamorphic virus is usually very large and complex. For example, W32/Simile consisted of over 14,000 lines of assembly language code, 90% of which is part of the metamorphic engine.[23][24]Avoiding bait files and other undesirable hostsA virus needs to infect hosts in order to spread further. In some cases, it might be a bad idea to infect a host program. For example, many antivirus programs perform an integrity check of their own code. Infecting such programs will therefore increase the likelihood that the virus is detected. For this reason, some viruses are programmed not to infect programs that are known to be part of antivirus software. Another type of host that viruses sometimes avoidare bait files. Bait files (or goat files) are files that are specially created by antivirus software, or by antivirus professionals themselves, to be infected by a virus. These files can be created for various reasons, all of which are related to the detection of the virus:∙Antivirus professionals can use bait files to take a sample of a virus (i.e. a copy of a program file that is infected by the virus). It is more practical to store and exchange a small, infected bait file, than to exchange a large application program that has been infected by the virus.∙Antivirus professionals can use bait files to study the behavior of a virus and evaluate detection methods. This is especially useful when the virus is polymorphic. In this case, the virus can be made to infect a large number of bait files. The infected files can be used to test whether a virus scanner detects all versions of the virus.∙Some antivirus software employ bait files that are accessed regularly. When these files are modified, the antivirus software warns the user that a virus is probably active on the system.Since bait files are used to detect the virus, or to make detection possible, a virus can benefit from not infecting them. Viruses typically do this by avoiding suspicious programs, such as small program files or programs that contain certain patterns of "garbage instructions".A related strategy to make baiting difficult is sparse infection. Sometimes, sparse infectors do not infect a host file that would be a suitable candidate for infection in other circumstances. Forexample, a virus can decide on a random basis whether to infect a file or not, or a virus can only infect host files on particular days of the week.Many users install anti-virus software that can detect and eliminate known viruses after the computer downloads or runs the executable. There are two common methods thatan anti-virus software application uses to detect viruses. The first, and by far the most common method of virus detection is using a list of virus signature definitions. This works by examining the content of the computer's memory (its RAM, and boot sectors) and the files stored on fixed or removable drives (hard drives, floppy drives), and comparing those files against a database of known virus "signatures". The disadvantage of this detection method is that users are only protected from viruses that pre-date their last virus definition update. The second method is to use a heuristic algorithm to find viruses based on common behaviors. This method has the ability to detect novel viruses that anti-virus security firms have yet to create a signature for.Some anti-virus programs are able to scan opened files in addition to sent and received email messages "on the fly" in a similar manner. This practice is known as "on-access scanning". Anti-virus software does not change the underlying capability of host software to transmit viruses. Users must update their software regularly to patch security holes. Anti-virus software also needs to be regularly updated in order to recognize the latest threats.One may also minimize the damage done by viruses by making regular backups of data (and the operating systems) on different media, that are either kept unconnected to the system (most of the time), read-only or not accessible for other reasons, such as using different file systems. This way, if data is lost through a virus, one can start again using the backup (which should preferably be recent).If a backup session on optical media like CD and DVD is closed, it becomes read-only and can no longer be affected by a virus (so long as a virus or infected file was not copied onto theCD/DVD). Likewise, an operating system on a bootable CD can be used to start the computer if the installed operating systems become unusable. Backups on removable media must be carefully inspected before restoration. The Gammima virus, for example, propagates via removable flash drives.[31][32]Recovery methodsA number of recovery options exist after a computer has a virus. These actions depend on the virus. Some may be safely removed by functions available in most anti-virus software products. Others may require re-installation of damaged programs. It is necessary to know the characteristics of the virus involved to take the correct action, and anti-virus products will identify known viruses precisely before trying to "dis-infect" a computer; otherwise such action could itself cause a lot of damage. New viruses that anti-virus researchers have not yet studied therefore present an ongoing problem, which requires anti-virus packages to be updated frequently.Virus removalOne possibility on Windows Me, Windows XP, Windows Vista and Windows 7 is a tool known as System Restore, which restores the registry and critical system files to a previous checkpoint. Often a virus will cause a system to hang, and a subsequent hard reboot will render a system restore point from the same day corrupt. Restore points from previous days should work provided the virus is not designed to corrupt the restore files and does not exist inprevious restore points.[33]Some viruses disable System Restore and other important tools such as Task Manager and Command Prompt. An example of a virus that does this is CiaDoor. Many such viruses can be removed by rebooting the computer, entering Windows safe mode, and then using system tools.Many websites run by anti-virus software companies provide free online virus scanning, with limited cleaning facilities (the purpose of the sites is to sell anti-virus products). Some websites allow a single suspicious file to be checked by many antivirus programs in one operation. Additionally, several capable antivirus software programs are available for free download from the internet (usually restricted to non-commercial use), and Microsoft provide a freeanti-malware utility that runs as part of their regular Windows update regime.Operating system reinstallationReinstalling the operating system is another approach to virus removal. It involves either reformatting the computer's hard drive and installing the OS and all programs from original media, or restoring the entire partition with a clean backup image. User data can be restored by booting from a live CD, or putting the hard drive into another computer and booting from its operating system, using great care not to infect the second computer by executing any infected programs on the original drive; and once the system has been restored precautions must be taken to avoid reinfection from a restored executable file.These methods are simple to do, may be faster than disinfecting a computer, and are guaranteed to remove any malware. If the operating system and programs must be reinstalled from scratch, the time and effort to reinstall, reconfigure, and restore user preferences must be taken into account.计算机病毒传播。

The original may modify the copies orthe copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable medium such as a floppy disk, CD, or USB drive. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses.A worm, however, can spread itself to other computers without needing to be transferred as part of a host. A Trojan horse is a file that appears harmless until executed. In contrast to viruses, Trojan horses do not insert their code into other computer files. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Today's viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative terminology in which a virus is any form of self-replicating malware.The term comes from the term virus in biology. A computer virus reproduces by making (possibly modified) copies of itself in the computer's memory, storage, or over a network. This is similar to the way a biological virus works.Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply replicate themselves and perhaps make their presence known by presenting text, video, or audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by legitimate programs. As a result, they often cause erratic behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss.There are many viruses operating in the general Internet today, and new ones are discovered every day.电脑病毒英文文章介绍三：噪音污染We know the sounds of cities are loud enough to cause great harm to people's hearing in the U. S. One person out of twenty has got some hearing loss. And all over the world the situation is getting worse and worse all the time since the noise increases with the population.With the development of machines, noise has also increased greatly in the 20th century. We live surrounded by loud planes, trucks and electric tools. TV sets and radios add up to 90 or J00 decibels, a certain unit used to measure the loudness of sound. A normal dialogue reaches 55 decibels; a plane goes to 100, and an ordinary train, reaching the station, can be twice as loud as the loudest plane. Disco music reaches about 118. At decibels the ear stops hearing sound, and pain starts.

The virus is an emerging concept in the traditionalThe virus was not classified network virus this concept, because the development of networks, the traditional virusThe network also has a number of characteristics. Today's Internet virus is a broad notion of aAs as long as it is carried out using the Internet to spread destruction can be known as network viruses, such as:"Love the back door", "Panda burning incense."Third, network virus and the distinction between computer virusThe original common computer virus is nothing more than the devastating formatted hard drive, delete systemWith the users documents, databases, etc. destruction. The mode of transmission is through nothing but also by virus infectionMutual copy of the software, carrying the virus, such as the use of pirated optical discs, such as infection disk systemsThe pilot virus and infected executable file virus, in addition to a network virus These are the common characteristics of the virus, but also steal users with remote data, remote control of the other sideComputers and other damaged properties, such as Trojan and consumption of funding the operation of the network computerSource collapse of the network server worm.Fourth, the network against virusNetwork destructive virus, will directly affect the work of the network, ranging from lowering speed videoRing for the efficiency of the network, while in the collapse, undermining the server information to a multi-year work destroyedDan. Because viruses and other network annually fraud led to economic losses of over 16 billion yuan,But this figure is constantly rising year by year. The next few years, the size of the market will reach Security60 billion yuan. One antivirus software experts pointed out: "Network avian flu virus even more." Such as: "XiongCat burning incense "In addition to virus infection through the web site users, the latest virus also through QQLoopholes in propagating itself through file-sharing networks, the default sharing, weak password systems, U disk and windowsForms bottom of the top mobile hard drives, and other means of communication. While LAN once a computer machineFor infection, it can spread through the entire network instant, or even within a very short period of time can be infectedThousands of computers, can lead to serious networks. Symptoms of poisoning in the performance of computersThere are enforceable. Exe files have become a strange pattern, the pattern shown as "PandaBurning incense, "and then System blue screen, restart the frequent, hard drive data destruction, serious entire companyAll computer LAN will all poisoning. "Panda burning incense," only more than half a month, a few varieties have highOf more than 50, and the number of its users infected constantly expanding. Makes infected, "Panda burn incense" diseaseThe personal drug users has been as high as several million people infected with a few more corporate users is rising exponentially. NetworkMore on the computer network the greater the harm caused by the virus.V. network transmission of the virus Features1. Infection fast: single machine environment, the virus can only be passed from one computer disketteTo another, and in the network can be adopted by the rapid spread of network communication mechanism. According to measurementSet against a typical PC network use in normal circumstances, once a computer workstation sickDrugs, and will be online within 10 minutes in the several hundreds of all infected computers.2. Proliferation of a wide range: in the network due to the spread of the virus very quickly and spread to encompass a large area, not only the rapid transmission of all LAN computer, but also through remote workstations virus in一瞬Inter spread to thousands of miles away.3. Dissemination in the form of complex and varied: computer viruses in general through the network "Station server workstation "channels of communication, but in the form of complex and diverse communication.4. Difficult to completely wipe: the standalone computer virus carriers sometimes can be deleted documentsOr low-level formatted drives, and other measures to eliminate the virus completely, and the network once a computer workClean stations failed to disinfect the entire network can be re-infected by the virus, or even just completed removalThe work of a workstation is likely to be on-line by another workstation virus infection. Therefore,Only workstations in addition to killing viruses, and can not solve the virus harm to the network is.6, the type of network virusAs the network increasingly developed, the type of network virus has been increasing, generally summed up asThe following categories:1.

The original may modify the copies or the copies may modify themselves, as occurs in a metamorphic virus. A virus can only spread from one computer to another when its host is taken to the uninfected computer, for instance by a user sending it over a network or carrying it on a removable medium such as a floppy disk, CD, or USB drive. Additionally, viruses can spread to other computers by infecting files on a network file system or a file system that is accessed by another computer. Viruses are sometimes confused with computer worms and Trojan horses. A worm, however, can spread itself to other computers without needing to be transferred as part of a host. A Trojan horse is a file that appears harmless until executed. In contrast to viruses, Trojan horses do not insert their code intoother computer files. Many personal computers are now connected to the Internet and to local-area networks, facilitating their spread. Todays viruses may also take advantage of network services such as the World Wide Web, e-mail, and file sharing systems to spread, blurring the line between viruses and worms. Furthermore, some sources use an alternative terminology in which a virus is any form of self-replicating malware.The term comes from the term virus in biology. A computer virus reproduces by making (possibly modified) copies of itself in the computers memory, storage, or over a network. This is similar to the way a biological virus works.Some viruses are programmed to damage the computer by damaging programs, deleting files, or reformatting the hard disk. Others are not designed to do any damage, but simply replicate themselves and perhaps make their presence known by presenting text, video, or audio messages. Even these benign viruses can create problems for the computer user. They typically take up computer memory used by legitimate programs. As a result, they often cause erratic behavior and can result in system crashes. In addition, many viruses are bug-ridden, and these bugs may lead to system crashes and data loss. There are many viruses operating in the general Internet today, and new ones are discovered every day.二：灰鸽子病毒Gray is a well-known dove back door. Compared to the older ice, black, gray pigeon can be said to be the back door of the home are a combination of different opinions. The rich and powerful functionality and flexibility of operation, well hidden so that others are to be outshone by the back door. Client simple and convenient to operate so that the entry of just a beginner can act as hackers. When used in legal cases, the gray pigeon is a good remote control software. However, if some of it to do illegal things, gray pigeons have become very powerful hacking tool. This is like powder, on various occasions, brought different. Gray dove to the complete presentation may be only a gray pigeon author to make it clear that we are here only for a brief.Gray Pigeon client and server are based on the preparation of Delphi. Hackers use of the client to configure a server program. Can be configured to include information on the type of line (for example, wait for the connection or take the initiative to connect), take the initiative to connect using the public network IP (domain name), a password to connect, the use of the port, the start of the name, the name of the service, the process of hidden ways, the use of the Shell, agents, icons and so on.Server for the client to connect a variety of ways, making the environment in a variety of network users may be poisoning, including local area network users (Internet through a proxy), the public network and ADSL users to dial-up users.As the gray dove to intercept the API call, in the normal mode file server and its services are registered to hide, that is to say, even if you set up a "show all hidden files" do not see them. In addition, the gray-end services doves of the file name can be customized, hand-All this has brought about the detection of certain difficulties.However, through careful observation, we found that the detection of gray pigeons still have to follow the law.From the above analysis we can see that principle to run, regardless of the custom server-side file name is what will normally be installed in the operating system directory in order to generate a "_hook.dll" at the end of the document. Through this, we can more accurately detect the hand-gray-end services doves.Due to the normal mode will hide their gray pigeons, so detection of gray pigeons must operate in a safe mode. Into the safe mode is: Start the computer in the Windows system into the start screen, press the F8 key (or in your computer holding down the Ctrl key), in the event of the start-up options menu, select "Safe Mode" Or "Safe1, dove gray as a result of the document itself has hidden attributes, so set Windows to show all files. Open "My Computer" menuselect "Tools" - "" Folder Options ", click" view "to remove" hide protected operating system files "before the Duigou, and the" hidden files and folders " Select the item "Show hidden files and folders," then click "OK."2, open the Windows "search files", enter the file name"_hook.dll"the search location to choose the Windows installation directory (for 98/xp default C: \ windows, 2k/NT for the C: \ Winnt).3, after a search, we have Windows directory (does not contain a subdirectory), the discovery of a document Game_Hook.dll.4, according to the analysis of the principle of gray pigeons, we know that if it is gray pigeons Game_Hook.DLL documents, the operating system is installed in the directory will be Game.exe and Game.dll document. Open the Windows directory, there are really two documents at the same time there is a record for keyboard operation GameKey.dll document.After a few steps which we operate on the basic of these documents can be gray-end services doves of the.Computer VirusA computer virus is a computer program that can copy itself and infect a computer without permission or knowledge of the user.

计算机病毒原理与防范文章英文文章
计算机病毒原理与防范文章英文文章Computer Virus: Principles and Prevention.In the 21st century, computers and their networks have become an integral part of our daily lives. From ordering pizza to managing hospitals and military defense systems, computers are used across a wide range of applications. However, with this increasing dependency comes a new threat: computer viruses. These malicious programs can wreak havoc on computer systems, steal personal information, and cause billions of dollars in losses. Understanding the principles of computer viruses and how to prevent them is crucial in today's digital world.What is a Computer Virus?A computer virus is a type of malicious software program that can replicate itself and infect a computer without the knowledge or permission of the user. These viruses can modify their copies or be modified themselves,as is the case with metamorphic viruses. Unlike biological viruses, computer viruses are not natural occurrences but are deliberately created by individuals exploiting the inherent vulnerabilities of computer software and hardware.How do Computer Viruses Work?Computer viruses typically spread through various channels such as floppy disks, hard drives, removable drives, and computer networks. Once a virus infects a computer, it can remain dormant for a period of time, acting like a time bomb, waiting for the right conditions to activate. When activated, a virus can infect other programs by inserting its code into them, altering their functionality, or deleting important files. The results can range from minor annoyances like pop-up ads to major disasters like system crashes and data loss.Types of Computer Viruses.There are several types of computer viruses, each with its own unique characteristics and behavior. File virusesinfect executable files such as COM, EXE, and DOC, while boot sector viruses target the start-up sector of a hard drive, preventing the system from booting properly. Network viruses spread through computer networks, infectingmultiple computers simultaneously. Macro viruses, on the other hand, infect documents created using word processing software and spread when those documents are shared or opened by unsuspecting users.Preventing Computer Viruses.Preventing computer viruses requires a multi-faceted approach. Here are some key tips to protect your computer from malicious software:1. Install and regularly update antivirus software: Antivirus software scans your computer for viruses and removes any detected threats. It is important to keep your antivirus software up to date to ensure it can detect the latest viruses.2. Use strong passwords: Avoid using simple or easilyguessable passwords for your computer and online accounts. Strong passwords make it harder for hackers to gain accessto your system.3. Be careful when opening email attachments and downloading files: Avoid opening email attachments or downloading files from unknown sources. These can often contain malicious software.4. Regularly backup your data: In case your computer is infected by a virus, having a recent backup of your datacan help you restore important information.5. Be cautious when using public Wi-Fi: Public Wi-Fi networks can be unsecured and easily compromised by hackers. Avoid conducting sensitive transactions or accessing personal information when using public Wi-Fi.In conclusion, computer viruses pose a significantthreat to the security and integrity of computer systems. Understanding their principles and taking proactive measures to prevent their spread is crucial in keeping yourcomputer and data safe. By following the tips outlined in this article, you can reduce the risk of becoming a victim of computer viruses and enjoy a safer, more secure computing experience.。
电脑病毒的中英文
电脑病毒的中英文Computer bugs are problems or mistakes in a program that wreak all sorts of computing havoc, but hunting for computer bugs doesn’t require a butterfly net or a can of Raid.Why do we call computer bugs “bugs”, anyway?As the story goes, pioneer computer programmer Admiral Grace Murray Hopper coined the phrase in the early 1940s, when her computer crashed. Searching for the cause of the problem, Admiral Hopper discovered the original computer bug, inside her computer, stuck in a crucial relay, was a dead moth.As she e*tracted the moth with tweezers, a colleague asked what she was doing. “I’m debugging the machine,”she answered, and the stuff of computer legend was born. The dead moth was taped into a notebook that logged computer problems, and now it’s preserved for posterity at the Virginia Naval Museum.Over the course of her Navy career, Admiral Grace Murray Hopper became known as Amazing Grace not only for her technical genius, but also for her ability topersuade people to try something new. Among other accomplishments, Admiral Hopper co-invented the COBOL computer language. COBOL, or Common Business Oriented Language, was the first computer language to use words instead of numbers.When Admiral Hopper first proposed a computer language using words, people said it wouldn’t work because computers didn’t understand English! However, she persisted, and COBOL revolutionized the computer industry by making computer language easier for programmers to understand. Amazing Grace helped make computers more user-friendly, easier to “de-bug,” and accessible for use not just in military research labs, but in homes, schools, and businesses.电脑漏洞〔computer bug，bug中文又有“臭虫，虫子”之意〕指的是会造成计算机中全部处理系统无法工作的程序问题或程序错误，但是寻捕电脑漏洞并不需要靠捕虫网或杀虫剂之类的东西。

Here's a brief essay on computer viruses:The Menace of Computer VirusesIn the digital age, computer viruses have become an unfortunate reality that every computer user must face. A computer virus is a type of malicious software that, once installed on a system, can cause a variety of problems.Origin and FunctioningComputer viruses are created by individuals with malicious intent. They are designed to infiltrate a computer system, often without the user's knowledge, and execute harmful actions. The virus can replicate itself and spread to other devices, either through network connections or removable media like USB drives.Types of VirusesThere are several types of computer viruses, each with its own set of characteristics and methods of operation. Somecommon types include:- Boot Sector Viruses: These viruses infect the boot sector of a hard drive, making it difficult for the computer tostart up properly.- Macro Viruses: These are written in the same programming language as the documents they infect, such as Microsoft Word's macro language.- Trojan Horses: Unlike other viruses, Trojans do not self-replicate. Instead, they trick users into installing them, often by disguising themselves as legitimate software.- Worms: These are self-replicating and can spread through networks without human interaction.Impact on UsersThe impact of a computer virus can be devastating. It can lead to loss of data, system crashes, and compromised security. In some cases, viruses can also steal sensitive information, such as passwords and financial details.Prevention and CureTo protect against computer viruses, it's essential to have robust antivirus software installed and regularly updated. Users should also practice safe computing habits, such as not opening suspicious emails or downloading files from untrusted sources. Regular backups can also mitigate the damage caused by a virus.If a virus is detected, it's crucial to isolate the infecteddevice from the network to prevent further spread and run a thorough virus scan to remove the threat.ConclusionWhile computer viruses pose a significant threat to the security and functionality of computer systems, with proper precautions and awareness, their impact can be minimized.It's the responsibility of every computer user to stay vigilant and protect their digital environment from these malicious entities.This essay provides an overview of what computer viruses are, their types, the problems they cause, and steps that can be taken to prevent and deal with them.。
计算机病毒原理与防范文章英文文章
计算机病毒原理与防范文章英文文章English:Computer viruses are malicious software programs that can replicate themselves and spread to other computers, causing harm to the system or stealing sensitive data. They can infect computers through various means, such as email attachments, downloads from untrustworthy websites, or removable storage devices. Once a computer is infected, the virus can execute its malicious code, leading to a range of issues, from annoying pop-ups to complete system failure. To prevent computer viruses, users should always keep their operating system and security software up to date, avoid clicking on suspicious links or emails, and refrain from downloading software from unknown sources. Additionally, regularly backing up important data can help minimize the impact of a potential virus attack.中文翻译:计算机病毒是恶意软件程序，可以自我复制并传播到其他计算机，对系统造成危害或窃取敏感数据。

接下来小编为大家整理了计算机病毒的介绍，希望对你有帮助哦!The computer virus is an outcome of the computer overgrowth in the 1980s. The cause of the term "computer virus" is the likeness between the biological virus and the evil program infected with computers. The origin of this term came from an American science fiction“The Adolescence of P-1”written by Thomas J. Ryan, published in 1977. Human viruses invade a living cell and turn it into a factory for manufacturing viruses. However, computer virusesare small programs. They replicate by attaching a copy of themselves to another program.Once attached to me host Program, the viruses then look for other programs to "infect". In this way, he virus can spread quickly throughout a hard disk or an entire organization when it infects a LAN or a multi-user system. At some point, determined by how the virus was programmed the virus attacks. The timing of the attack can be linked to a number of situations, including a certain time or date, the presence of a particular file, the security privilege level of the user, and the number of times a file is used. Likewise, the mode of attack varies. So-called "benign" viruses might simply display a message, like the one that infected IBM's main computer system last Christmas with a season's greeting. Malignant viruses are designed to damage the system. The attack is to wipe out data, to delete flies, or to format the hard disk.What Kind of Viruses Are There? There are four main types of viruses: shell, intrusive, operating system and source ode. Shell viruses wrap themselves around a host program and don'tmodify the original program. Shell programs are easy to write, which is why about half of viruses are of this type. Intrusive viruses Invade an existing program and actually insert a portion of themselves into the host program. Intrusive viruses are hard to write and very difficult to remove without damaging the host file.计算机病毒是八十年代计算机飞速发展带来的结果，计算机病毒这一名词起因于在计算机上传染的有害程序与生物学中病毒的相似性，该名词起源于1977年出版的、由 Thomas J. Ryan写的一本美国科幻小说《p-1的青春》。

The second class is system or boot-record infectors: those viruses, which infect executable code, found in certain system areas on a disk that are not ordinary files. On DOS systems, there are ordinary boot-sector viruses, which infect only the DOS boot sector on diskettes. Examples include Brain, Stoned, Empire, Azusa, and Michelangelo. Such viruses are always resident viruses.
File infectors can be either direct action or resident. A direct-action virus selects one or more other programs to infect each other time the program which contains it is executed ,and thereafter infects other programs when “they” are executed (as in the case of the Jerusalem) or when certain other conditions are fulfilled. The Vienna is an example of a direct-action virus. Most other viruses are resident.
What are the main types of viruses?

Generally, there are two main classes of viruses. The first class consists of the file Infectors which attach themselves to ordinary program files. These usually infect arbitrary .COM and/or .EXE programs, though some can infect any program for which execution is reuested, such as .SYS,.OVL,.PRG,&.MNU files.
File system or cluster viruses (e.g. Dir-II) are those that modify directory table entries so that the virus is loaded and executed before the desired program is. Note that the program itself is not physically altered; only the directory entry is. Some consider these infectors to be a third category of viruses, while others consider them to be a sub-category of the file infectors.
Finally, a few viruses are able to infect both (the Teuila virus is one example). There are often called “multipartite” viruses, though there has been criticism of this name; another name is “boot-and -file” virus.
Computer viruses are bits of code that damage or erase information, files, or software programs in your computer, much like viruses that infect humans, computer viruses can spread, and your computer can catch a virus when you download an infected file from the Internet or copy an infected file from a diskette. Once the viruses is embedded into your computer?s files, it can immediately start to damage or destroy information, or it can wait for a particular date or event to trigger its activity.
d Cohen?s well-known definition, a computer virus is a computer program that can infect other computer programs by modifying them in such a way as to include a (possibly evolved) copy of itself. Note that a program does not have to perform outright damage (such as deleting or corrupting files) in order to be called a “virus”. However, Cohen uses the terms within his definition (e.g. “program” and “modify”) a bit differently from the way most anti-virus researchers use them, and classifies as viruses some things which most of us would not consider viruses.
What are macro viruses?
Many applications provide the functionality to create macros. A ma
