Interesting Occurrence

[Brent_OKeeffe () asc aon com]

Okay... Here is a new one for me.  Got a call from my dad saying he left 
his PC on last night connected to his broadband.  He went to log in this 
morning and noticed a new ID in his user list - IWAP_WWW.  He immediately 
deleted is and called me.  I had him ensure his critical updates we all 
applied - they were.  I had him ensure his antivirus was up to date - it 
was (Norton Antivirus 2004).  He is running XP Home.

I searched the antivirus sites and elsewhere for references.  Any idea if 
there is a new vulnerability that has not been publicly released?  Any 
clues?
