    Antimalware Service Executable has high CPU and memory usage 24/7


    I have been experiencing very high CPU and memory usage because of Window's own *Antimalware Service Executable* program. I've pretty much tried everything that I've seen on websites like setting daily schedules for scans and even changing my antivirus, but nothing works. I'm out of options and I'm asking for your help. Please reply only if you have a decent way of fixing this, even better if you've experienced this yourself. Thank you.

    :)

    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?
