I found this note on a demonic torrent site.
Fake DRM
There have been reports of torrents including an info file that states that the file came from XXXXXX.com, and that you need to 'install a DRM identifier' in order to play a video file. Those files are fakes, and someone is trying to make you install some trojan. If you come accross one of those, delete them and report them in the tracker or indexing site you got them from so they can remove them
Thanks
