Windows 10: What is this "Antimalware Core Service" that suddenly appeared on my system?

I'm afraid that this is a virus or something. I recently noticed that "Antimalware Core Service" is now running in my task manager, and until recently I've never seen this before in the couple years that I've been using Windows 11. Opening the file location goes here, and the files were created 8/7/2024, so they're definitely recent.I can't right click and end the task like other critical Windows tasks, which makes me think it's somehow an official Windows task and is completely harmless, but I'm not sure.I also don't see why this would suddenly pop up because I haven't updated my computer in

Antimalware Service Executable

Hello,

Currently I'm facing a problem with the antimalware service executable. It uses half of my memory, I did tried some solutions such as: Change Windows Defender’s schedule and Add Antimalware Service Executable to Windows Defender exclusion list. However, none of these solutions has yet fixed my issue. Any help is appreciated.

Should I install another antivirus program?
