Question about Antivirus for File Servers

Hello All,

What is the recommendation on Antivirus for Windows file servers? I am setting up 2008r2 file servers for my university and was planning on using System Center Endpoint Protection 2012, if that would be appropriate. Are there any exclusions that should be setup, like when configuring DC,DNS,other servers?

I have done some searching here on the forums and done a little Googling but haven't found any specific recomendations. Yes we have AV on our workstations, but still want to run some sort of AV directly on the file servers.

Thanks in advance i for your time.
