We have been seeing an increase in emails like this one below. While the Sender, Subject, and wallet ID change, these emails have a lot of things in common...
They are a hoax. While it's TRUE that your computer could be infected by malware, the method of that infection is often something you were complicit in. Opening dangerous attachments, visiting websites which requested you install "viewer software" or similar, failing to maintain your computer's antivirus, and security updates, etc.
When your computer suffers from an actual ransomware attack, you will normally receive a popup on the computer itself or a file on your desktop with instructions. The reason these people send you an email, is that it is the only thing they are capable of doing. Their hope is that by sending thousands of emails that they will trick you into sending them money.
IF you follow their instructions to send them money, there is no way to get it back, and you will have given them futher reason to continue the hoax.
Your anti-virus or anti-spam software may not block all these emails. In general, the more sensitive the software, the more likely there are false positives - which might be ok for some people, but sometimes not for people in business who might have legitimate reasons for using the very keywords these emails might contain.

Subject: Why your antivirus did not detect malware?
[Seemingly random characters - actually a BTC Wallet ID]
Hello! As you may have noticed, If you are not familiar with this, I will explain.
September 28, 08:49 AM GMT+1
Trojan Virus gives me full access and control over a computer or other device.
This means that I can see everything on your screen, turn on the camera and microphone, but you do not know about it. I also have access to all your contacts and all your correspondence.
Why your antivirus did not detect malware?
Answer: My malware uses the driver, I update its signatures every 4 hours so that your antivirus is silent.
This means that I have full access to your device. I've been watching you for a few months now.
The fact is that you were infected with malware through an adult site that you visited. I made a video showing how you satisfy yourself in the left half of the screen, and in the right half you see the video that you watched.
With one click of the mouse, I can send this video to all your emails and contacts on social networks. If you want to prevent this, transfer the amount of $717 to my bitcoin address (if you do not know how to do this, write to Google: "Buy Bitcoin").
My bitcoin address (BTC Wallet) is: [Seemingly random characters - actually a BTC Wallet ID]
Filing a complaint somewhere does not make sense because this email cannot be tracked like my bitcoin address.
If I find that you have shared this message with someone else, the video will be immediately distributed.
