I wonder whether anyone could help me, please

This happens also while the PC is idle.

I’ve installed a third party antivirus, but, in TaskManager, I can still see Microsoft Win11’s “Antimalware Service Executable” still using around 148 MBs of RAM.

How can I mitigate Win11’s Antimalware Service Executable’s RAM consumption??

In advance, thank you very much
