Troubleshooting computers that slow down when System Center Endpoint Protection is running scans.
How do i troubleshoot and find the cause of these types of problems?

UPDATE: 03.09.2015:
It turns out my problems seem to be unrelated to System Center Endpoint Protection virus scanning.
And i am currently investigation Windows Update / Definition Updates searching for or installing new updates as a potential cause.

I have updated the WIndows Update Client on most of my machines and i am currently waiting for results. So far it looks good.

Someone also posted a Hotfix in this thread which i will try if this does not help my users. Thanks for the help so far.

As I stated above the hotfix took care of the earlier problem we experienced but...

I am now noticing on some machines when they run a full scan and hit a recovery partition on the machine called (Q:\FactoryRecovery\cdrivebackup.wim) it is crashing the Antimalware service and not starting back up. This recovery partition is common to Lenovo products and every machine with this partition is crashing the Antimalware service. It never did this in the past. Anyone else see this problem with recovery partitions,drive or directories.
