Desktop I've been hacked pls help

So I just got hacked the guy is saying he would upload some videos of me pleasuring myself nd whatnot but I don't believe that since the time he gave me passed a long time ago and he continues to send the emails. The thing is he is sending those with my own mail, because he did actually hack my accounts and stuff, and he is leaving them as drafts, I've been changing the password but he still manages to send more. In the mail it says something about the trojan is in the drive so am I f'up? I am scanning my conputer with malwarebytes in safe mode and allat. pls help if you know something bc it is rather annoying
