Windows Defender woes

[Alec19]

Hey everyone,

 

Recently I have had some problems with Windows Defender. Approximately every 15 minutes Windows Defender moves to the top of the task manager list for CPU usage. It puts a full load on one of my CPU cores and spikes up to 65 °C for about 1.5 minutes ramping up my CPU fan in the process. I am assuming that this is a background quick scan, but I do not know (the last background scan time reported by Windows Defender does not always match up with these events). I created a new trigger for it so that it only does it when I sign out but it still triggers every 15 minutes. It is most noticeable when idling.

 

I am currently running an i9-10850k on Windows 10 Education edition version 10.0.19042.

 

Does this make any sense? I know antivirus software takes some horsepower but pegging my 10 core CPU seems wrong to me.

 

I would just like it to either reduce the frequency of scans or reduce the impact on the CPU.

Any suggestions?

 

Thanks,

Alec

Hi, i'm Renata Bliss. Have you checked Windows Updates for any cumulative updates?

Does it still do this after a reboot?

Check for windows updates and do a full scan.

Sorry for the delayed response. I have run multiple full scans with nothing found. Restarting does not have any effect and I keep windows up to date so I am not behind on an updates.

 

Thanks,
