I remember that when I installed ESET a year ago, Windows defender ram usage dropped, just installed ESET on another system two days ago and it deactivated defender automatically. but defender is still using about 150MB of ram. is that normal? is there any way to reduce its ram usage without completely deactivating it?

Defender is mostly dormant, waiting to accept new Platform or Definition updates in the background or in case it needs to be re-enabled when ESET gets uninstalled.
