Garyb, I had to remove NAV a long time ago...
Well, I survived untill now... I'm avast since then
I did not have to reinstall "Windows Script 5.6" or anything related.
You can delete folders/files under either 'Norton' or 'Symantec' folder, the others under Liveupdate folders and ApplicationData...
On Registry, well good Registry Cleaners could do some work.
But, for me,
the only thing I would worry about is the VDD keys. You must have the following entry there:
C:\Program Files\Alwil Software\Avast4\aswMonVd.dllCan you post the contents of these Windows Registry keys in your system?
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\VirtualDeviceDrivers\\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\VirtualDeviceDrivers\\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\VirtualDeviceDrivers\\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet003\Control\VirtualDeviceDrivers\\VDD
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet004\Control\VirtualDeviceDrivers\\VDD
Well, I'll be 'out' of forums for some days... if you can wait
