Open the Defender control panel (I have this as an icon on my desktop) - the executable is in c:\program files\windows defender\msascui.exe
In the Options Setting - scroll down to the "Real-time protection options" and uncheck the box that says "Use real-time protection".
This computer is dedicated to real time data acquisition and display - no email - minimal internet use etc. So I run the batch mode virus checker once every week or two - no surprise - no viruses detected ;-).
This decreased memory usage AND improved the download/calculation speed since the CPUs weren't spending time checking for viruses in my real time data download.
