So here's the deal. I just upgraded to a SBS 2008 domain controller from Windows 2000 server. Clients are is currently using an older version of Symantec Antivirus supporting server/ client model that continues to update definitions and push them out to the clients. To clear up any confusion the server piece of this Antivirus is running on a Windows Server 2003 box. In addition the SBS 2008 box is getting it's exchange e-mail filtered through a 3rd party so I don't feel we need to implement an antivirus solution for Exchange or a spam filtering solution for that matter. On a test server, I successfully installed Comodo free antivirus, I thought I'd give this a shot because it is free for both commercial and personal use. My question is, can I make this work as far as exclusions go? Has anyone had experience doing this and / or can you lead me to a list of exclusions that I should list for this particular piece of AV software with this OS? Thanks!
