The malware gave me full access and control over your system, meaning, I can see everything on your screen, turn on yourcamera or microphone and you won't even notice about it. I have also access to all your contacts. I made a video showing both you (through your webcam) and the video you were watching (onthe screen) while statisfying yourself. I can send this video to all your contacts (email, social network)! You can prevent me from doing this. To stop me, transfer exactly 700$ with the current (BTC) BITCOIN price, to my bitcoin address. If you do not know how to do this, Google - "How to buy Bitcoin". My bitcoin adress is: {BLOCKED}WZYQrz5Z9S9X7nYNueznU7iU5V5h.
