I am running Windows 7, 64bit with 12 GB of RAM. My memory usage is usually around 2-3 GB. About once a day, Windows Defender eats all my memory. For a few minutes the computer is slow (even if running i7-980) then Defender releases the memory and everything is back to normal. I know it's Windows Defender because as soon as I see memory going high, if I stop the Windows Defender service, the memory goes right back to normal.
Is there anything I can do except disabling the service?
