I have a computer that most files have been encrypted. The virus left behind in each directory a howdecrypt.txt document and a howdecrypt.jpg file saying to go to http://www.torproject.org/projects/torbrowser.html.en and install the browser then enter address: 4sfxctgp53imlvzk.onion. Follw instructions. Guaranteed recovery is provided within 10 days.
Has anyone encountered this before?
