History Of Computer Viruses

A computer virus is the nightmare of every computer user. It is a computer program that can replicate itself and corrupt a computer, attacking several programs depending on its severity. Virus is, in common, a general term for all kinds of such programs, malware and spyware, although the latter do not have the ability to replicate.
