Hacker sent an email to me that appeared to have been sent by myself to myself. Threatened to release some kind of private data, pictures and website visit content to my associates. The hacker requested that I pay $900 to the bitcoin account to keep them quiet. And, when the funds were received that they would remove or delete the Trojan from my computer OS. If the funds were not received within 48 hours they would delete my files and send whatever they think they have to all of my associates.
