The McAfee VirusScan Enterprise for Linux 1.9.x/2.0.x On-Access scanner must be configured to find unknown program viruses.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-63003	DTAVSEL-005	SV-77493r1_rule		Medium

Description
Due to the ability of malware to mutate after infection, standard anti-virus signatures may not be able to catch new strains or variants of the malware. Typically, these strains and variants will share unique characteristics with others in their virus family. By using a generic signature to detect the shared characteristics, using wildcards where differences lie, the generic signature can detect viruses even if they are padded with extra, meaningless code. This method of detection is Heuristic detection.
