Cluster Virus

A type of computer virus that associates itself with the execution of programs by modifying directory table entries to ensure the virus itself will start when any program on the computer system is started. If infected with a cluster virus it will appear as if every program on the computer system is infected; however, a cluster virus is only in one place on the system.
