You're more than welcome. I knew something must be wrong with that program. Actually, maybe it just need to be reconfigured (actually, properly configured and adapted to your specific needs), but this way it gives you just troubles, nothing else. It looks like it's made to protect your system, but c'mon... protecting your system by not letting you install one of the best antiviruses out there, that's unforgivable.
Again, I'm glad you solved your problem, and you almost went to other antivirus
You see ? Sometimes, you just need to calm down a little bit, try to think what programs could be causing the problem, and solution is always somewhere out there. We are here to help, but you should stick around as well. Now, you have enough experience with that program (Processes Guard), and you could help someone else with possible exact the same problem in the future
Take care !
