A computer virus is a computer program that can copy itself 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 a floppy disk, CD, DVD, or USB

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.
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 root kits, spyware, dishonest adware and other malicious and 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.
