If you are switching to win2k be sure to get ALL the updates from the windows.com site. I didn't and someone got into my system through a hole and was deleting files when I came back into the room with my coffee. It was a nightmare. I have just now got everything back online...sigh. Just do your updates in a timely manner and you should be ok. I also installed a router so I would have a physical firewall, but if you can't afford that get the program esafe from www.esafe.com It's free. Marque
