I don't like CCAV. It's sort of fine on my tablet that hardly gets anything new installed, but on PC, it's just too annoying. I've updated BitTorrent Sync and it spawned like 15 popups on installer temp files that even if you trust permanently doesn't help much because it asks for each individual file on its own. And you can't even turn off Auto-Sandbox and just use it as a cloud antivirus, because then the entire interface and trey icon is in red, triggering my OCD. So I was forced to go back to CIS because it has smart Auto-Sandboxing rules that treats safe local files as trusted and stuff spawned from them the same. Which is nice for such updating situations or when I'm compiling my own apps so I don't have to deal with popups every time I make a small modification and compile it (because it otherwise gets treated as new unique app every time).
