    Antimalware Service Executable problem

    I am still having the problem even with the latest prerelease build. The Antimalware Service Executable process is often running and taking a lot of CPU, disk and memory. The same The Antimalware Service Executable -> Windows Defender Service ...
    Too often the PC (an I7 one, 8 GB EliteBook HP) is stuck and even the response of a keyboard entry is very slow!!

    Any suggestions?

    Antimalware Service Executable using 90% CPU

    Antimalware Service Executable High CPU

    I am experiencing high CPU usage on the Antimalware Service Executable on my Surface Pro i7 1 tb (2017). This has been going on for a couple of months. It makes my computer almost unusable. The CPU sits at 100% any time I try to use it. The CPU has
    over 50% usage when nothing is being run in the foreground all the time (24 hours a day). The April update was just installed and the Antimalware Service Executable is still running at over 40% of the CPU utilization.
