Each capability of ProcessGuard is powerful in its own right and could almost warrant its own program. For example, a program which could block rootkit trojans from installing would be very valuable on its own, yet this is just one feature of ProcessGuard. Here is just a brief list of some of the main uses of ProcessGuard:
  
     Securing processes from being attacked (terminated, suspended, modified)
     Controlling which programs are/aren't allow to run 
     Blocking rootkits and other malicious drivers from installing
     Protecting physical memory from modification
     Blocking hooks and code injections
     Determining which programs are being executed on your system
     Determining which programs are attacking others on your system
     Analysing the inter-process behaviors of programs
     Keeping a log of all programs that execute (important for post-infection analysis)

Main attacks ProcessGuard blocks ...
ProcessGuard protects against so many different types of attacks that it's difficult to combine them all into one list (for example, although it protects against process termination it secures over a dozen different "termination vectors" in order to accomplish this, so really it's protecting you against a lot more than just one attack).
 
Here are the main classes of attacks that ProcessGuard can protect against:
     Unwanted/unknown process execution
     Process/service termination
     Process/service suspension
     Process/code modification
     Process/service crashing
     Rootkit trojan installation
     Firewall leaktest bypass methods
     Hooks and code injections
     Physical memory malicious modifications
     Windows File Protection attacks
     User Imitation attacks

Without a kernel-level, strategic security solution like ProcessGuard your system and the security software you run on it is vulnerable. ProcessGuard not only secures itself and the other processes on your system, it also secures your other security programs, allowing them to do their job without risk of termination or attack. ProcessGuard also protects any programs with internet access from FWB attacks!
