DiamondCS ProcessGuard is a groundbreaking Sécurité Système 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 Système. 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. ProcessGuard even stops most keyloggers and leaktests, and is recognised by many to be the most comprehensive anti-rootkit solution available.

Sécurité-conscious users on the Internet these days typically have a firewall and antivirus program at the very least, yet very few users are aware that these layers of Sécurité can easily be rendered null and void simply by terminating or modifying the host process. For example, a trojan could simply terminate your personal firewall before attempting to transmit your personal details over the Internet, effectively rendering the firewall useless and leaving the user with a false sense of Sécurité. Likewise, it could modify your antivirus program by patching it in memory so that it no longer detected any viruses, so even with a Banque de données update and even if it was a known trojan it would remain undetected. Rootkits are another serious threat, because once they've infected your Système they can often be extremely difficult to detect (as they modify the operating Système itself in order to hide, effectively becoming a stealth trojan). ProcessGuard allows you to block the installation of rootkit drivers, preventing any infection from occurring. Firewall bypass techniques are also another big Sécurité problem where ProcessGuard can lend a hand. These are just some of the many advantages you'll get from securing your Système with ProcessGuard.
