Symantec Antivirus 10 was installed by the previous consultants before me. The scanner and System Center Console has been installed on our Exchange server. Does Symantec 10 even scan the Information Store to prevent virus attachments? We're currently using the evaluation version of Ninja Email Security, should we be using that for antivirus instead? What about preventing viruses that may infect outside of the information store, such as something that could travel through the network from another workstation/server?
