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

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-63039	DTAVSEL-103	SV-77529r1_rule		Medium

Description
Interpreted viruses are executed by an application. Within this subcategory, macro viruses take advantage of the capabilities of applications' macro programming language to infect application documents and document templates, while scripting viruses infect scripts that are understood by scripting languages processed by services on the OS. Many attackers use toolkits containing several different types of utilities and scripts that can be used to probe and attack hosts. Scanning for unknown macro viruses will mitigate zero-day attacks.
