Sorry to hear that, but all we can do is trying to get avast pay attention to your ticket/request.
About two years ago handling tickets was really horrible.
14 days or more or no response at all.
Moroni took over things and things really improved a lot.
Almost all tickets where handled in 1-3 business days.
Sure, with the major blooper avast made with the way they introduced the SafeZone browser to the users of the free version, I can imagine the stack of tickets grew a lot in a very short time.
But soon the handling was back to within a normal/acceptable time.
Since +/- 3 months the waiting time increased a lot and I really mean a lot !
All that avast is saying is "due to the increase of tickets it will take us longer to handle them" without mentioning a estimated time or telling what has caused the increase of tickets.
It would not surprise me at all if it has to do with the "screw-ups" in the latest versions/(micro) fixes.
It is already not possible anymore for users of the free product to create a ticket.
Really sad to see basically doesn't give any support anymore to them and it is especially sad that avast never told they would stop giving support through the ticket system.
