2000? The most insecure version of NT ever!

There's this service or protocol meant for recieving 'useful' messages from Microsoft (probaly ads and stuff) but has been used to send pop up spam and malware. Seriously, your computer will get owned in minutes! Used to use 2000 before XP and I had to block it with the firewall, but it still eats your network bandwidth. Evil!! :rant:
