How Artemis works
The Artemis feature uses heuristics to check for suspicious files. It provides users with Windows-based McAfee anti-virus products that have the most up-to-date real-time detections for certain malware.
Artemis does not provide protection for entire classes of malware; just for suspicious samples. The benefit of protecting against specific threats is the capability to protect users with McAfee security at virtually the same time that McAfee Labs determines a sample is malicious.
You can configure the administrator-configured sensitivity levels Artemis uses to look for suspicious programs and DLLs running on client systems protected by VirusScan Enterprise. When Artemis detects a suspicious program, it sends a DNS request containing a fingerprint of the suspicious file to a central database server hosted by McAfee Labs.
