A computer virus is a computer program that can copy itself[1] and infect a computer. 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 the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as afloppy disk, CD, DVD, or USB drive.[2]

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 another computer.[3][4]

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 reproductive ability. Malware includes computer viruses, computer worms, Trojan horses, most rootkits, spyware, dishonest adware and other malicious and unwanted software, including true viruses.

There are many types of computer viruses:

File virus : Most viruses fall into this category. A virus attaches itself to a file, usually a program file.

Boot sector virus : These viruses infect floppy and hard drives. The virus program will load first, before the operating system.

Macro Virus : This is a new type of virus that use an application's own macro programming feature to distribute themselves. Unlike other viruses, macro viruses do not infect programs; they infect documents.

Virus Hoax : Although there are thousands of viruses discovered each year, there are still some that only exist in the imaginations of the public and the press - known as virus hoaxes. These viruses hoaxes DO NOT EXIST, despite rumor of their creation and distribution.
