I've heard from a friend that Spotify got attacked by an hacker, which results in it "damaging the hard disks" and stealing private data of the computers where the program is installed. It allegedly does that through a backdoor, though it seems to be just a rumor, as no official communication of that was given by developers.
If I used Comodo Sandbox from Comodo Internet Security, would that prevent the backdoor application from damaging or deleting data from the hard drive, or reading private data?
