ProcessGuard is a powerful new type of security system that secures Windows at the lowest (kernel) level, allowing it to provide the maximum possible security. An intuitive interface makes the program very easy to use, and a comprehensive help file explains everything in full detail for those wanting to know more. ProcessGuard gives you full control over which programs are allowed to run and prevents even the stealthiest rootkit Trojan horses from being able to install malicious drivers. Virtually all known code/process-related attacks can be prevented, including keyloggers, firewall leak tests, process termination, code and DLL injection, thread hijacking, and Windows File Protection attacks.
