This is not my pc, I am helping someone out with this problem. Win7 Home Premium V6.1 (Build 7601 SP1)
It started when she checked her bitdefender from the taskbar, noticed it disappeared and had not been running. Went to start BitDefender and found it had been disabled, and effort to re-enable result in error message saying Bitdefender is blocked by group policy. She gets on the phone with tech support which offers a free upgrade to the newest 2013 version, but the error comes up again when attempting to uninstall during the new install process. Control panel uninstall gives the same error. I notice sandboxie default browser and control panel do not start and give same error. Malware bytes Pro finds nothing, housecall finds nothing, hitman pro finds nothing.
I am not sure where to even begin, this is a personal PC with no Group Policy, gpedit.msc does not exist as it's not even offered in this version of windows....what to do???
