It would appear this is a common problem. Paid $80+ for them to solve my problem but still have it AVG Security comes on for 20 minutes at start up and then again at intervals when I am using my computer and freezes everything for another 20 minutes. I even went in to Settings to check I would do it manually but it keeps coming up. If it can't be solved my next step is to delete hundreds of dollars of faulty security programs.
