ok, first of all, this is an RAT most likely. do a system restore NOW, and take your webcam and microphone OFF YOUR COMPUTER. don't just turn them off, because RAT's can turn them on and look at you and hear you.
close ANYTHING that connects to the internet except your browser.
now, keyloggers are included in RAT's, so don't go off about that.
anyone who has any information at all POST HERE. this is bad.
also, botting into safe mode helps.
