Hack, of course I want all the protection I can get/need. Unfortunately, I don't know what protection I can/should get. I feel completely stupid on this subject, but I am willing to endure shameful torment if means I get the answers I need to make a good decision.

Nightwalker, thank you for your suggestion. It seems AVG makes picking a server antivirus software easier than most. They just have file server antivirus and email server antivirus. Since I won't be using exchange, I am guessing the file server antivirus is all I need. Of course, that is why I am asking this question here since I don't really have any concrete confirmation that this is all I need.

Are there any network admins that have some good advice for me? I don't really want to contact a sales rep because they will probably just try to sell me on everything they can get me to buy.
