3.0 Configure and Install SCEP Antimalware Policies

To be performed by SCCM Administrators and security team

SCEP Client policies define where the client can obtain the defintion updates, when does it perform scans, and what files are scanned.
In order to create a new policy, right click on Assets and Compliance and click on Create Antimalware Policy. As a best practice, a new policy should be created and deployed to a limited number of computers using a collection.

 The SCCM Antimalware Policy allows us to set the following options:
  • Scheduled Scans
  • Scan Settings
  • Default Actions
  • Real-Time Protection
  • Exclusion Settings
  • Advanced Settings
  • Threat Overrides
  • Microsoft Active Protection Service
  • Definition updates
The section below provides the best practice settings for the Antimalware Policy settings. The details of each scan setting are available at the following link:
