Antimalware Server

One Primary Server needs to be designated as the Antimalware Server to perform Antimalware-related maintenance tasks for your zone. This server also functions as an Ondemand Content Master (OCM) by default. If you designate one or more additional Primary servers as OCMs in the zone, the OCM designation can be removed from the server selected here as the Antimalware Server. You can make that change via the Server Hierarchy configuration.

Any Primary Server designated as an OCM needs to meet the Ondemand Content Master requirements. For more information, see Ondemand Content Master - Requirements.
