McAfee VirusScan Access Protection Rules Common Standard Protection must be set to block and report when common programs are run from the Temp folder.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-42523	DTAM145	SV-55251r2_rule		Medium

Description
This rule will block any executable from running from the Temp directory; however, this rule is much more restrictive in that it stops nearly all processes from launching in the Temp folder. Most viruses need to be run once by a person before infecting a computer. This can be done in many ways, such as opening an executable attachment in an email or downloading a program from the Internet. An executable needs to exist on the disk before Windows can run it. A common way for applications to achieve this is to save the file in the user's or system's Temp directory and then run it. One purpose of this rule is to enforce advice that is frequently given to users: "don't open attachments from email." The other purpose of this rule is to close security holes introduced by application bugs. Older versions of Outlook and Internet Explorer are notorious for automatically executing code without the user needing to do anything but preview an email or view a website.
