Hello there,


We're encounter a strange problem with our Windows Defender and SCEP in our company.

Everything run fine till 1-2 weeks ago.


We manage our Windows Defender or SCEP through SCCM. There we have policies that limit CPU usage at 30%.


Excluded is also the Windows Defender folder (C:\Program Files\Windows Defender) and MsMpEng.exe process.



What is happening during a scheduled full scan is, that during 2-4 minutes the MsMpEng.exe is using as it should only 30% of the CPU. But then, suddenly is taking the complete CPU that is left causing the CPU to be at 100%. Most of the cases, Windows is freezing and nothing can be done anymore. In some rare cases, you can use Windows but in slow slow mode.



Does anyone encounter the same problem and found a solution for this?


Thanks a lot for your help.


Greetings


Nicolas
