What is computer virus?
A computer virus is a small program which is designed to infect an operating system for damaging or corrupting data, changing data, or degrading the performance of your system by utilizing resources such as memory or disk space. In addition, it is allowed by its designer to replicate itself and continue to infect another operating system. The group of computer virus includes Spyware, Adware, Keyloggers, Trojans, Worms, Hijackers, Rootkits, Password Stealers, Tracking Threats, and Rogue Antispyware. A computer virus can only spread from one computer to another 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 drive. 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.
