|It seemed like when AVAST was running yesterday the C drive appeard all used up temporarily but returned to normal with 18GB free when AVAST finished whatever it was doing.|
I didn't remove external drive but turned it off and rebooted just now and C drive still shows 100% used - this is wrong - can't be all used. AVAST does not appear to be running at this time.
I'm confused. I am also wondering what I can do to get the external drive operating at normal speed.
