Can't save or attach files in sandbox

I use Open Office and somehow it has been placed in sandox, at least I think that is what happened. I did not want to place it there but now I cannot save any open office writer files I create nor can I attach them to emails. How do I get sandbox to leave me alone? Thanks. I am obviously not to tech savvy.

By “sandbox” do you mean avast has put it in “Quarantine”.
What Avast alert or error message did you get?

Which Avast product are you using?

I am using Avast Security Premium. I don’t see a “quarantine” message. The Open Office app opens up surrounded by a bow with “Avast Sandbox” at the top left. I can create docs without problem but I cannot save them or attach them to emails. This never used to happen, so I must have inadvertently changed a setting somewhere.

oops! surrounded by a box, not a bow.
