I have a computer running Windows Server 2003. I would like to put some sort of antivirus software on it, but I was just wondering what good antivirus software is available for Windows Server.

ANSWER: Bit Defender 9 Internet Security is the best antivirus solution. My main hobby is antivirus testing and I have proved that Bit Defender is the best antivirus. There are both free and paid versions of Bit Defender. It is a award winning antivirus product. It is very easy to update because the size of updates are less and new virus signatures are released every half an hour.)
