Norton Anti-virus

My Mum & Dad just got their first computer running XP Home and they
bought Norton anti-everything!

They keep getting a message popping up from the toolbar saying "Rules
automatically created for the program: Microsoft Generic Hot Process
for Win 32 service".

It disappears after a few seconds but is very annoying.

I presume it is Norton 'learning' or 'accommodating' windows functions
but can the popups be switched off and if so how. Presume eventually
they will cease.

Any help appreciated.
