Did you uninstall LiveUpdate as well?
There are components in NAV which must also be completely uninstalled, before you attempt to reinstall (cleanly I might add, don't install over the top of an existing install) NAV.
Items such as
LiveReg,
LiveUpdate and Norton AntiVirus (2000, 01, 02, 03, 04, corporate, whichever) must be uninstalled individually, through Control Panel, and the system restarted before you try and install (freshly) another copy of NAV itself.
/edit
There are also "LiveUpdate" time-bomb removers and such 'extenders', but it is not up to me to decide if you want to do this or not, I'm just saying that there are 'ways' around such matters, however, Symantec and the Norton line of AV software do need support, and you should subscribe (legally) to receive virus definitions.
