I believe that the last thing you should do is delete (even if that were possible).

Deletion isn’t really a good first option (you have none left), ‘first do no harm’ don’t delete, send virus to the chest (a protected area) and investigate.

In this case it most certainly needs further investigation by someone with the inner workings of avast (a team member) as I have been unable to replicate the problem.

I don’t know why it might be restricted to a small number of people (not that that is any less important) or we would have seen a much larger activity in the forums. I have tried to get someone to look at this topic, other than that I’m helpless as an avast user not developer.
