I am looking for a straightforward antivirus product for a single computer running Microsoft's Small Business Server 2003 operating system.
For the best response, try posting in the Symantec Enterprise Forums for AntiVirus.
Norton AntiVirus/Internet Security/360 doesn't work on Windows Server systems.
You have to use Symantec AntiVirus (Endpoint Protection)
