In my opinion, autosandbox warning box is shown for a lot of applications very often and I think heuristic is too strict. Unfortunately, vlk & other viruslab guys do this on purpose (marketing). I'd like to see autosnx box only when avast is really not sure about the application which is going to be executed. I'm sure, most our avast free users (where autosnx feature is included) don't have a clue what's the sandbox and how it works. They just need silent antivirus, running in background and without additional configuration - showing annoying popups don't really help.
