Oh, I fully understand that. I'm a user experience/digital product designer for a living. I don't have anything wrong with change; in fact, I enjoy it sometimes. But from a UX standpoint, this is a stupid design decision. Now I will be having two scans scheduled if I want to control a custom one, the other of which I cannot control (the Full Scan). For now, I just changed the priority of my Full Scan to low, so it doesn't run in the evening when I'm trying to chill and play some video games on my PC. Not gonna bother scheduling a custom scan, since it'll get the same job done.
A simple question? Once you know your computer is secure, why are all these scans needed 
Your AV scans anything new, changed or in other ways accessed.
I was wondering if it did that! If it does, that makes me feel better. I don't pay attention to how long it takes.
