Title

McAfee VirusScan On-Demand scan must be configured to find unknown macro threats. (Cat II impact)

Discussion

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. The scanning for unknown macro viruses will mitigate zero day attacks.
