I have Avast IS, current and licensed. I can’t find Safe Zone, it does not show up in the “Components” section of settings, nor the “Modify” section in the Control Panel.
Oh, just realised this is in the wrong section, if someone kind could move it please. 
My question was answered ther so no need for this topic - sorry guys.
Do you mean the SafeZone Browser is missing ?
If so, then the old SZ browser has been withdrawn before a new SZ browser is introduced.
EDIT: I have seen something else that seems to indicate it might only be in the Premium version, which would seem to be bad news. More so if one of the reasons of getting AIS was for the SafeZone.
