hello friend, well, avast virus chest is divided in three sections, infected files, system files and user files, so u need to see where are they located, so we can help u. Because, when u select virus bault, it lists the files that are in the three sections, u need to expand virus vault to see where are located. If they are in system files, everything is ok, but if they are in infected files, u need to send a copy to avast support team, so they can analize them. Take care pal!
