I installed windows 2003 Server today, however the antivirus (kaspersky) and firewall (zonealarm) which I used when I had XP or 2000 Pro does not work in windows 2003 server. Just wanted to know is there any other good antivirus and good firewall that can work on windows 2003 server?

and where can I download them?

Thanx in advance

I can't speak to the quality of the products, but a quick search turned up Sophos Anti-Virus and InJoy Firewall, both of which claim to support Windows 2003 Server. 30-day evaluations are available for download.
