Additionally, Microsoft Forefront Client Security ended its life cycle on July 14th 2015.
Therefore, no definition updates will be available in the future for Forefront Client Security.
"Because of this, we recommend that you always install the Configuration Manager hotfix or cumulative updates that contain the latest anti-malware platform updates to re-set the baseline in Forefront Endpoint Protection 2010 Update Rollup 1 and Configuration Manager 2012 SP1/R2, even if you wish to use SUM as the primary deployment method for anti-malware platform updates," Lv explained.
In keeping with that theme, Cumulative Update 1 for System Center 2012 R2 Configuration Manager was released this week.
Updates to System Center 2012 Endpoint Protection, as well as the older Forefront Endpoint Protection solution, will be released three times per year, starting on April 8.
