If they've been sandboxed (chest, in Avast terms).....

Not really. They've been isolated.

From Wikipedia "The virus chest is quarantine folder where "infected files" can be stored. The chest causes the files' usage to be disabled and is meant to prevent them from causing any harm. The virus chest also stores vital system files to prevent them from virus damage. They still can be run, but the access to the file by any source or other program is blocked until it is removed from the chest."
