[NAV] Intelligent Updater

Hi everyone,
recently I can no longer run Liveupdate on my Norton Antivirus 2002, I
know it's dated and am wondering if some of you are using it.
I wonder if Symantec decided to stop releasing virus definition for
that product, before buying an update I'm curious if anyone has ever
experienced that.
I tried to download the stand-alone updater but it's the same story.

Ironically I also have ZoneAlarm which is not able to update the
integrated antivirus but can download any other update (anti-spyware
etc.)

Maybe I got a virus that prevents antivirus to update or is this a
simple coincidence?

Thanks in advance for your help
