As you may have noticed, I sent this email from your email account (if you didn't see, check the from email id). In other words, I have full access to your email account.
I infected you with a malware a few months back when you visited an adult site, and since then, I have been observing your actions. The malware gave me full access and control over your system, meaning, I can see everything on your screen, turn on your camera or microphone, and you won't even notice about it. I also have access to all your contacts.
Why your antivirus did not detect malware? It's simple. My malware updates its signature every 10 minutes, and there is nothing your antivirus can do about it.
