Show Summary Details

Quick Reference

The most common form of virus. It functions by adding program code to the code of the computer which has been infected. It usually alters the start-up file of the infected computer so that the virus code is executed first before the normal code which starts up the computer. Such a virus is activated when the computer is first booted up after infection; the virus code then carries out some potentially destructive act such as deleting important files.
