Windows 10: high CPU usage antimalware service everytime on Start up

Hello! As the title describes, since the 1909 update the antimalware service is using too much cpu (70%) and slowing the pc down for about 2-3 minutes before going to normal.


How can i solve this problem?

Thanks.

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?
