As you may have noticed, I sent this email from your email account. In other words, I have fullccess to your email account. I infected you with a malware a few months back when you visited an adult site, and since then, I have been observing your actions. The malware gave me full access and control over your system, meaning, I can see everything on your screen, turn on your camera or microphon and you wont even notice about it. I also have access to all your contacts. Why your antivirus did not detect malware? Its simple. My malware updates its signature every 10 minutes, and there is nothing your antivirus can do about it. I made a video showing both you (through your webcam) and the video you were watching (on the screen) while satisfying yourself. With one click, I can send this video to all your contacts (email, social network, and messengers you use). To stop me, transfer $976 to my bitcoin address. My bitcoin address (BTC Wallet) is 158RQmxLtxZaY11TEy6utfhbWWVmWLnSq2
