Windows 10: Microsoft Windows Defender using high resources suddenly

Out of the blue, Antimalware Service Executable has suddenly began using over 750mb of RAM, a constant 1-2mb of disk writing, and 1-5% of my CPU.While this is a small portion of what I have available, this sudden spike is concerning, it only started noticeably a few days ago. I've attempted rescheduling the scans, and adding itself to exclusion, with no luck. I've also used MD to scan, and Malwarebytes as well to scan, with nothing out of the ordinary.I've done diskm, and sfc scans, with nothing spiking.I'd like to know what it is doing, or how to remedy this. I did recently-ish update windows

Do you use Windows Defender?

I used to use AVG but that thing seemed like a resource hog! Windows defender is only spyware protection *Frown

I use Microsoft Security Essentials now which does Anti Virus and Spyware protection. Its free so long as your copy of Windows passes Genuine Validation. Its quick and doesn't seem to hog up as much resources. *Toast :toast:
