A computer virus is malware that seeks to alter the normal functioning of your computer without permission or knowledge of the user.

The virus usually replace other executable files infected with this code.

Viruses can destroy, intentionally, the data stored on a computer, although other more harmless, which is only known for being annoying.

Computer viruses are basically function to propagate through the software, do not replicate themselves because they do not have that power [citation needed] as the worm, are very harmful and some also contain a payload (payload) with different objectives, from a simple prank to do serious damage to systems or computer networks block generating useless traffic.

The operation of a computer virus is conceptually simple. It runs a program that is infected, in most cases, ignorance of the user. The virus code is resident (staying) in the RAM of the computer, even if it contained the program has finished running.

The virus then takes control of basic operating system, infecting so later, they are called executable files to run. Finally add the code of the virus infected the program is recorded on the disc, which replicated the process is complete.
