From ID Theft Protect:
IDTP Guard provides protection against zero-day attacks that cannot be identified or removed by typical Antivirus software. IDTP Guard is a proactive solution, which identifies malicious software attempting to run on an infected system and based on what it does rather that what it is. Antivirus works to identify malware based on signature files and scanning the system for known threats. IDTP Guard provides a solution against unknown threats which have no current signature file to remove them from the system.
