I was trying to download an update for my "Quick Play"- HP recommended. The moment I pressed the download button, this attack appeared in my security history file. I ran security in safe mode, at about 300,000, computer became hot, and I stopped the scan to let it cool. Nothing showed. MS RPCSS ATTACK (UDP) Very serious remote computer attack, I know Windows 2000 is affected, the server, XP not Vista...?
