I am only posting this to possibly help someone else if they are having problems. I disabled PG, shut it down. Then went into safe mode uninstalled PG ,went into Windows System32 removed pguard.dat and pghash.dat. PG wouldn't install. Removed the Process Guard folder. Then I used Regseeker to search for Process Guard and found 5 entries in registry and removed them. Then it installed. For some reason things seem to get left on my system after an uninstall.
