Norton Antivirus Woes

Windows XP machine with Nortons 2004 Antivirus loaded.
Nortons caught a virus and quarantined the file. It took all the saved emails with it. This is not the problem. The problem is that, now, Nortons no longer works. If you open it, it locks up immediately. It pops up error messages that go away too fast to read what they are.
The only error message that stays long enough to read suggests that Nortons be uninstalled and then reinstalled. It will not uninstall. I have tried several means of uninstalling this application and can not get it to uninstall.
Anybody know a way, short of formatting the drive, to get nortons off this machine?
