SCEP Antimalware service stops frequently then prompts to start the service

Recently we've noticed on multiple servers that the antimalware service suddenly stops.  I can restart it only for it to stop again within what I can tell a few short hours.  We are alerted that the 'antimalware service is not running, or the antimalware engine is corrupted. To restart the service, run the recovery task in Health Explorer.'  I've tried updating the definitions which didn't help and ran a full scan.  I also ran a scan off of Microsoft Safety Scanner which netted 0 results found.  This started a few weeks ago. 

Anything else I can check besides re-installing the client?  As far as I know, this could get worse and I can't tell why this is happening on these servers and I'd like to understand the cause.  All servers are running Windows Server 2012 R2 and we use Configuration Manager 2012 R2 SP1 to manage the client.
