Antivirus for Win Server 2003 R2 Std Ed

Hello Everybody!

Could you guys please tell me which is the best Antivirus for Windows Server 2003 R2 Standard Edition?

Or what is the best protection for a server that will store files, an internet gateway?

Im afraid to connect this server to internet without first installing antivirus.

And also can anyone provide me a weblink as to what unnecessary services I can shutdown, and the right permissions I have to configure, etc?

Hoping for anyone’s immediate response.

Many Thanks in Advance
