A computer virus is a form of malicious software that piggybacks onto legitimate application code in order to spread and reproduce itself. A virus, as noted, is specifically a kind of malware that infects other applications and can only run when they run. In most cases, applications that have been infected by virus code are transferred from computer to computer just like any other application. Many viruses include a logic bombcode that ensures that the virus’s payload only executes at a specific time or under certain conditionsusers or admins may be unaware that their applications are infected.”]
