I once tried it few months ago and didn't find it either. I didn't look hard enough so I might have missed it. But now that you're not finding it either, I guess they use a different name for that feature which we are not familiar with. They offer plenty of customizability so I would be surprised if they don't have a feature to turn it off.
I used it since a lot of months with 2 old laptops (win 10). It run very smoothly and it's very light on the systems. There is a lot of customizations. I don't suffer of false positives.
For me, it's a good install and forget.
Only the gui is totally outdated.
A few weeks ago, I moved from AVG to K7 on an aging HP laptop running Window 7 Pro. When I installed K7 it was like my laptop was born again. This HP now runs like when it was brand new & "state of the art." Shazam!
