    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.

    Antimalware Service Executable, high cpu, memory and disk usage

    I'm having the high CPU usage and it appears that antimalware service executable is to blame. Yes, I had Norton installed and used the removal tool. What do you think could be the problem?
