From the developer:
DiamondCS ProcessGuard is a groundbreaking security system first released late in 2003 that protects Windows processes from attacks by other spyware processes, services, drivers, and other forms of executing code on your system. ProcessGuard also stops applications from executing without the users consent, stops malicious worms and trojans from being executed silently in the background, as well as a variety of other attacks.
