Of course.
Did you already uninstall NAV?
Maybe it won’t be necessary to uninstall all Norton Internet Security right now.
Let’s do it by parts…
After that, post what do you have in this following registry keys (maybe you don’t have all of them):
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\VirtualDeviceDrivers
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\VirtualDeviceDrivers
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\VirtualDeviceDrivers
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers
Probably you will have avast driver (if you’re lucky) and Symantec drivers listed there. I need only the full path of the drivers (probably: C:\Program files\Symantec\S32EVNT1.DLL and C:\Program files\Alwil Software\Avast4\aswMonVd.dll).
By now, don’t delete any key of registry. Let’s do it by parts and slowly. ok?
