Follow these steps depending on your answer.
If your password was weak that's what for your account hacked. Make it more stronger and hard to guess.
Blid did it was martin18. Think if you have ever downloaded something from him. If you have he could of infected your machine with a Trojan. With a Trojan he can record your keyboard... see you through a webcam, hear you from your Mic, control your computer.....
You would need to reinstall Windows to be 100% clean of virus... or you could hope the Trojan doesn't have a back up dns/ IP and use netstat dos command then see all the connections and block the IP in your host file.
Well good luck! Let me know if you need help.
