add-on virus

add-on virus 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.
