Configuring file scanner updating
Applies to: Forefront Security for SharePoint
The standard FSSP license includes a number 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 FSSP service starts. Unless you disable the updating of a specific engine, it will always be automatically updated. It is recommended that you allow all the licensed engines to update, even if a particular engine is not used in any of your scan jobs.
For more information about updating scanners, see the "File scanner updating" chapter of the "Microsoft Forefront Security for SharePoint User Guide".
