Norton Security always using 50% of my CPU

Hi! I hope someone can assist me. Did a lot of research about this, found lots a things to try out but so far no results. Installed version 22.5.2.15 with all updates refreshed installed on Windows 10 OS. I disabled all optimization disk options and defrag because a lot of people mentioned that could help.

I have 3 computers in my house, all 3 under the same OS and same Norton Security product. Only one of them is doing this weird high CPU usage all the time. Tried a full reinstall, no change. Never had other crap antivirus installed on this PC. Previous Norton product installed was 360.

Any help will be appreciated.
