VIRUS

A computer virus is a computer program that can replicate itself 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.

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.

 As stated above, the term "computer virus" is sometimes used as a catch-all phrase to include all types of malware, even those that do not have the ability to replicate themselves. 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.

An example of a virus which is not a malware, but is putatively benevolent is Fred Cohen's compression virus. However, antivirus professionals do not accept the concept of benevolent viruses, as any desired function can be implemented without involving a virus (automatic compression, for instance, is available under the Windows operating system at the choice of the user). Any virus will by definition make unauthorised changes to a computer, which is undesirable even if no damage is done or intended.
