Will This person really Expose me due to the Trojan Virus?

So recently I was just checking my emails and I ran into my Spam and there was an email I didnt recognize so obviously I had to check it out. They said they started tracking my internet activities and they have access to all of my stuff and that I have 48 hrs to pay or they expose me. They said that when they were gathering information about me they found out that im a huge fan of adult websites but im not. They said not to reply, not to contact police, security services and to not tell my friends, not to reinstall the OS. They also said they have access to all the controllers of my devices, microphone,video camera and phone due to the Trojan virus. So will they be able to send stuff about me or have any information?
