    Antimalware occupies High CPU usage with Fan noise


    Hi


    Windows defender identified the following malware in my pc and removed it


    Detected:VirTool:Win32/DefenderTamperingRestore

    Status: Removed or restored.

    affected items :regkeyvalue: hklm\software\policies\microsoft\windows defender\real-time protection\\DisableBehaviorMonitoring


    I ran full scan afterwards, in addition to Malware bytes scans. All came up with no threats detected.


    But now my computer triggers antimalware service right after I open a browser window and the CPU usage goes higher with Continuous fan noise.


    I have tried to stop the task ,modify it via Admin templates and even turn it off from setting ,including file exclusion of MSMPEng.exe.


    Nothing changes this loop of Antimalware service with high noise. System restore did not work . Neither did scanning from startup .


    Any Suggestions will be appreciated.


    Thanks

    :)

  3. high CPU usage antimalware service everytime on Start up

    Hi Casemiro,

    As this is your only line of defense, we can change the timing in which this does a scan. Right now the task is probably set to when you start up your computer - we could change it to later at night or some other time if you'd like?

    Seeing above you can change the task scheduler event; do not remove Windows Defender as this is your only defence.

    There some changes you can make to ensure that this doesn't run at max CPU usage.

    Let me know if this fixes your issue.

    VERY HIGH CPU USAGE

    Hey there Kristian, first I'd suggest using your task manager and seeing if Windows antimalware executable is going on, because it can spike high cpu usage rates. Afterwords, i'd like for you to do a scan with your windows defender, as it may be malware
    infecting your computer.
