Norton Antivirus stop working

Hi! I have a problem with Norton Antivirus. It was working fine for 3 years, but since a week ago it stopped working. No Norton Antivirus icon on the notification area and if I want to open the Norton Antivirus icon from the desktop, nothing happen.

Things I have done:

  • Uninstalling and reinstalling (not working)
  • Using the Norton Removal Tool, restarting, reinstalling (not working)

Another thing I’ve noted is that a new icon, Norton Identity Safe, and always appears after uninstalling and reinstalling. I contacted the Norton Support (spanish) and they could not help, and the logmein application that they use for remote assistence did not work.

EDIT: It is a Windows XP machine, working fine until some days ago.
