What is a computer virus?

A computer virus is a type of computer program that can be copied by itself without the user's permission or idea. Like mutated viruses, they can modify copies of actual viruses or modify copies themselves. A virus can spread from one computer to another only when the infected computer is transferred to a normal computer.

For example, a user can transmit a virus through a network or spread it through a portable device such as a floppy disk, CD, USB drive, or the Internet. Viruses can also infect a network file system, infecting other computers that use that system.

Viruses are sometimes associated with computer worms and Trojan horses. A Trojan horse is a file that remains intact until executed.
