I have a client with a Windows Server 2003. It is used only to run a set of applications from one manufacturer. The rest of the company data sits on the nas. Nothing else happens on the server. I have been searching for an antivirus program. We used to use AVG for file server and know the renewals is for how many users on the network and it gets quite expensive. All the workstations are running workgroup and not domain and have there own anitivirus. Looking for recommendations?????
