I read online this could be fixed by turning off Windows Defender I have other anti-virus software installed. However, even with Windows Defender turned off, "Antimalware Service Executable > Microsoft Defender Antivirus Service" remains listed on Tas

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.
