Windows 10: Antimalware Service Executable taking up high CPU for several hours!

    Antimalware Service Executable taking up high CPU for several hours!


    A service called Antimalware Executable takes up about 30 % of my CPU. It doesn't normally do this, and I tried following the tutorials on how to disable in the task schedule and registry (I use Win10 Home and thus cannot use Group Policy).

    I also tried including an exeption in its scan, so it does not scan itself.

    But it still takes up a lot of CPU.

    How do I fix the high cpu usage?

    But they say you cannot turn Windows Defender off in group policy in Home.

    My problem is that Antimalware Service Executable is still running, still taking up a lot of CPU. Please help me!

    Yes, I know. I already read these tutorials (and countless others). They all say the same, but it does not work. Windows Defender still use up 30 % of my CPU no matter whatever I do!

    Please somebody help me! What's the reason none of these tutorials work for me?!?

    Maybe if you post your system specs in the required spot, we will have something to go by. I have Defender turned on and It is not using any CPU resources at the moment.

    No, it usually did not for me either, until today.

    Posting system specs is a little off-topic, because my problem is that even though I do this step:
    https://support.microsoft.com/en-us/...nder-antivirus

    - The Antimalware Service Executable still runs high. I have a pretty good CPU and this has never been a problem until today.

    My computer is neither new or old. It was installed 1 years ago. I never had any problems until today.

    I did this step:

    Open Windows Defender Security Center, then select Virus & threat protection > Threat settings.

    Turn off Real-time protection.


    • Note: Scheduled scans will continue to run. However, files that are downloaded or installed will not be scanned.

    That "note" is my problem... it still scans, and it is still scanning while I am writing this.

    I already set the Exclusions to the Windows Defender path. Did not work either.

    No it is not off topic. When you joined this Forum you were asked to fill them out. We are not mind readers. All you have in it is "windows 10"..
