Norton Antivirus 2002 on my brother's computer will not auto-protect - it doesn't load up into Windows XP system tray even when you tell it to. It won't do a full system scan, it starts and then just stops, it won't do a live update, and it won't let you set the auto-protect to ON. It had previously been working and he can't remember when the icon stopped appearing in the system tray. He uninstalled it and reinstalled but it still won't work. He's also run a virus scan from the symantec web-site but that didn't find anything wrong. Has anyone got any ideas please as I'm getting fed up with all the phone calls !!
