Ok guys here is my setup.

First my web and mail servers are both outsourced and offsite. The only server I am running is a Dell 2600 Rackmount with RedHat 9 installed. This server does domain logins and file storage. I would like this server to also be able to scan for viruses on all shares.

We have around 23 computers using domain logon and half of them actually do any type of regular work with network shares. I would like to protect all 23 of these machines as best as possible against viruses, adware and spam. Currently spam blocking is not needed, but I'm sure it will be soon.

Users have seperate accounts on the outsource mail server. This may endup being changed to a postmaster server depending on the problems i have implementing a spam blocker system. Currently the provider does not scan any e-mail for anything. Users get their e-mail through (gag) Outlook.

I am using a Netgear FR114P router to connect to our broadband connection. This router has a builtin firewall and IDS (using Stateful Packet Detection).

I would love central management of the antivirus system. I want to use our server to do this, so it appears to me norton may not work. I have not found anywhere where it says there is a scanner for Linux systems or central management on a Linux server. I would even go with web based central management if necessary, but I really dont want to add a second box using windows just for antivirus management.

Thats my story need any more info just let me know.

Thanks for all the help and attention guys.
