How heuristic network check for suspicious files
works
This feature provides customers using Windows-based McAfee anti-virus products with the most
up-to-date real-time detections for certain malware. It uses administrator-configured sensitivity
levels to look for suspicious programs and DLLs running on client systems that are protected
by VirusScan Enterprise. When the real-time malware defense detects a suspicious program, it
sends a DNS request containing a fingerprint of the suspicious file to a central database server
hosted by McAfee Avert Labs. The real-time defense feature does not provide protection for
entire classes of malware; just for suspicious samples. The benefit of protecting against specific
threats is our capability to protect users with McAfee security at virtually the same time that
McAfee Avert Labs determines a sample is malicious. In this release, the feature is disabled by
default. You must select a sensitivity level to enable the feature.
