I'm setting up an evaluation copy of windows 2000 server at my home for learning purposes. I plan to alow it access to the internet through the DMZ function on my Linksys router so I'd llike to put antivirus and a software firewall on it. Unfortunatly free versions or worstation copies of software are normally smart enough to know that they are running on a server and will not install.

Do you know of any free antivirus and most important free firewall software that I can use on 2000 server? Anything is better than nothing so any suggestions are welcome. Thanks.
