Forefront Security file scanner updating


Applies to: Forefront Security for Exchange Server

The standard Microsoft® Forefront™ Security for Exchange Server license includes a standard set of antivirus engines, of which four are enabled, in addition to the Microsoft Antimalware Engine. These engines begin scanning your system as soon as the FSE service starts. Unless you disable updating a specific engine, all are always automatically updated.


It is recommended that you schedule updates and do a manual update before scanning with an engine that you have not used before.

For more information about updating scanners, see the File Scanner Updating chapter of the "Microsoft Forefront Security for Exchange Server User Guide."
