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

Security-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 security 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 security. Likewise, it could
modify your antivirus program by patching it in memory
so that it no longer detected any viruses, so even with
a database update and even if it was a known trojan it
would remain undetected. Rootkits are another serious
threat, because once they've infected your system they
can often be extremely difficult to detect (as they
modify the operating system 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
security problem where ProcessGuard can lend a hand.
These are just some of the many advantages you'll get
from securing your system with ProcessGuard.
