Avast not opening unknown apps in sandbox when running them for the first time

Hello,

I’ve noticed a weird behavior with Avast sandboxing and scanning new and unknown apps. I am playing a game “Cataclysm: Dark Days Ahead” on their experimental branch, which updates a few times a day. As such this game’s executable is constantly changing. Avast is noticing that and sandboxing it for a few seconds to make sure it is safe which I applaud.

My problem is with the fact that this tends to happen only on the second time I run a new version of the game, which would be an issue if the executable did contain malware. I don’t know if it is a quirk of my computer or this game, as I’ve not really noticed the sandboxing behavior with other apps I run, however I’ve decided to share it in case it is an unknown issue
