DTAM090 - McAfee VirusScan On-Access Scanner General Settings must be configured to enable scanning of scripts.
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 script that can be used to probe and attack hosts. (NIST SP 800-83) The scanning of scripts is crucial in preventing these attacks.
