WinPatrol for Windows

WinPatrol warns you about hijackings, malware attacks, and other critical changes that may be made to your computer without permission. WinPatrol is a multipurpose support utility that replaces many system utilities with enhanced functionality.

WinPatrol was the first to use a heuristic behavioral approach for detecting attacks and violations in your computing environment. Traditional security programs scan your hard disk looking for known threats. WinPatrol captures snapshots of your critical system resources, and alerts you to any unnoticed changes.

While others update their signature/definition data files, you'll be removing potentially dangerous programs.
