I have been using the Avast antivirus from the past several years and it has been protecting my computer well without any issues and increases the performance as much as possible. Whenever the new threat locates, sometimes it cleans or deletes but sometimes it quarantines into a "chest”. I don’t know where the chest is located. I need to find out because I have by mistake put one item in that and I need to remove it from there. Can anyone help me?
