The Antimalware Service Executable process plays an important role in the Windows Defender Service that comes bundled with Windows 10 (and, despite the similarities in name, is completely unrelated to Emsisoft Anti-Malware!). However, it’s also infamous for consuming far more than its fair share of CPU processing power, and can even single handedly reduce your computer’s speed to a glacial crawl.

If you’re a Windows Defender user and have noticed high CPU usage for abnormally long periods of time, you’ll be pleased to know that the issue can easily be resolved.

In this article, we’ve put together a few simple steps you can follow to prevent Antimalware Service Executablefrom hogging your system’s resources and keep your machine running smoothly.

Thanks, I use Emsisoft today (thanks to the MT draw) but I've already used WD as the main AV, and I actually noticed that gigantic use of CPU was one reason I have changed. Changing the subject, how cool it is to see Umbra working at Emsisoft, a guy who was one of the moderators of our beloved MT, I'm very happy for you, my friend, keep being this cool guy that you are, and excellent professional, big hug and always success

I gave WD a lot of chances, but eventually gave up on it, because of this.
I prefer Fix #3. I also disable services, because they kept taking CPU sometimes.
