I've got a home customer using a HP Touchsmart computer that randomly started having certain applications blocked by group policy; AVG, Malwarebytes, Quicken installer to name a few. I do not see any programs being blocked under gpedit->Computer Configuration->Windows Settings->Security Settings->Software Restriction Policies - or- Application Control Policies->AppLocker.
These programs appear to function properly in safe mode. The computer is NOT part of a domain (just a standard workgroup), nor has it ever been. The user is an administrator on the computer.
I was able to download this
which allows me to 'unlock' the station and allows all software to run properly, but don't want to have to tell a customer that he has to run that every time he restarted the computer. Once the computer was 'unlocked' I ran full scans of the computer with CCleaner, AVG, Malwarebytes, and TDSSKiller, all of which came back clean, these scans were also all run in safemode.
Are there any suggestions/places to look? I'm kinda at a loss for where else to look.
