This should only be required if you run into any strange problems with Process Guard that doesn't allow you to boot into your operating system normally. 1) Reboot your operating system into SAFE-MODE. To do this Reboot your machine, and just after your BIOS screen disappears keep pressing the F8 key. A menu should appear, select "Safe Mode" and press Enter. 2) Run Process Guard's uninstall utility. You can see this from the Start Menu -> Process Guard -> Uninstall. 3) To verify the removal, make sure procguard.sys does not exist in (c:\windows\system32\drivers) directory, and that procguard.dll and pguard.dat are not in your system32 directory (c:\windows\system32). If they still exist delete them. 4) Reboot your machine and Process Guard should now be removed.
