Thanks Alot

 

remove all norton products, then delete all norton folders in programs file folder, then reinstall windows

 

symantec a/virus ect.

 

Run REGEDIT

Browse to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\SharedDLLs
If the right window, scroll until you find C:\Program Files\Symantec\SYMEVNT.386
Select it, right mouse, delete

Browse to
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\VxD\SYMEVNT
Select it, right mouse, delete

There is no reason to reinstall Windows.

BTW I "presume" that you have just uninstalled Norton Antivirus????
