This is important and a good clear distinction. I know that Patrick 
disagrees with me (dnd Steve too I think) but this description truly 
makes the distinction.

And THAT is the key. No matter how often you scan no matter how up to 
date that scan was. Files could be placed with a virus, then accessed 
with that virus and the spread is on. Rather like testing negative for 
COVID and then not wearing a mask, after all you can't spread what you 
don't have, right? BUT that test was only a moment in time.

With the scan on write and scan on open it gets scanned every time AND 
no matter where it lives. New directories need not be added to some scan 
and no specific knowledge of what files are stored where is required.
