Add option to check file by Virustotal before you / Jami open(s) it
Not sure if it's a good idea when it comes to privacy:
But would a opt-in setting within Jami be useful that every file (including voice/video messages) a specific contact sends you will be first uploaded to virustotal and if there a no results Jami will open it.
Otherwise Jami will delete the file (after a warning message)?
