@olddog: Deep Screen is a feature enabled as a default Avast! v9 setting. It is visible to an average user as shown in the picture.
Most probably, in its current state, it screens (sandbox analysis) based on the following factors listed here:
-

Deep Screen would analyse an unknown program in the sandbox for about 15 secs before terminating it.
Depending on analysis, the program would either be
a) quarantined
b) restarted if it does not perform any suspicious behaviour within the sandbox.
If (b) occurs, the program should function properly on restart, done automatically by Deep Screen (no user input).
Note that Deep Screen would automatically add the program to exclusions in this case.
