Hi Bal,

Click the Start button, type "regedit", and then press Enter.
Create registry backup by exporting them (to be sure).

Delete whole registry keys responsible for this situation:

Software restriction policy
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Safer
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\Windows

Group restriction policy
HKLM\Software\Policies\Microsoft Key (looks like a folder)
HKCU\Software\Policies\Microsoft Key
HKCU\Software\Microsoft\Windows\CurrentVersion\Group Policy Objects Key
HKCU\Software\Microsoft\Windows\CurrentVersion\Policiess Key

After that restat PC, AVG should be ok, but I reccomend run whole computer scan.

Thanks

Hi Zbynek,
Installed GMER and ran the test but my PC hanged twice with Blue screen. It keeps crashing. Is there any other way out?

Thanks
