Symantec has a Norton removal tool named RNAV that you use to remove it and then reinstall it.
As this is another post, I will make that assumption this is not the machine you posted about a 98 hang on boot.
During bootup an error message comes up.
C:\PROGRA~1\NORTON~1\NAVAPW32.EXE is not a valid Win32 application.
HOW DO I FIX THIS...
