You're curious about why the antimalware service uses so much CPU on your Ryzen 5 3500 with 16GB DDR4 RAM at 3200MHz. You're right—fixing it is possible, but understanding why the solution helps can be tricky. Adding Windows Defender to the exclusions might seem odd, but sometimes it prevents the antivirus from scanning certain files or processes, which can reduce unnecessary load. It's possible a glitch causes the antivirus to run itself constantly, and blocking those files temporarily gives it a break. Microsoft may not address this directly because it’s a minor issue for most users.
Including itself in exclusions may temporarily halt the problem but doesn't ensure a permanent fix; it could revert once the issue resurfaces later. MS products often overlook numerous known problems over time.
It's normal for your disk to perform this action during data transfers like downloads or file extraction.
It then halts scanning completely once you include it in the exclusions, without affecting other functions.
