Are you running server 2008 on your laptop or 1 box and don’t want to pay a bunch of money for antivirus? I have some Virtual Servers running 2003 and 2008 server for testing. I want them to be protected. Below are download links to ClamWin and Rising Antivirus. They are both free and are compatible on a server OS. I recently installed ClamWin on my 2008 servers. It has been running with no problems and does not slow down my servers. I have not installed Rising antivirus but is compatible.
Here are the links to download them:
