Antimalware Service Executable is using 80% of my CPU. I've tried everything to stop it: disabling Windows Defender, adding the file to the exclusion list, and running a full malware scan, but nothing works. The only temporary fix is ending the process in Task Manager. This issue started a few days ago, possibly after an update. Setting the affinity to one core didn't help either. It seems like it needs to be fixed by an upcoming update.
