Hi,
We have SCCM 2012 R2 with FEP role with Windows 8.1 Clients.
When there is any malware detected on client system , then the FEP's Default action is not applied which we set to remove from SCCM antimwlare policy.
It stays forever with RED message "PC Status: At risk" and i have click manually on "Clean PC" button.
It was working fine with SCCM 2007 R3 and antimalware was deleted automatically
I have Set All default acttion to Remove from SCCM Antimalware Policy
