I've never actually had ransomware but I have had a few emails claiming it's there and they've been using my web cam to record my online porn viewing and they will email that video of me watching it and me 'ahem' to all my email contacts if I didn't pay the Bitcoin. At first I was worried because they knew an old password of mine which I hadn't used in ages and that it didn't matter if I'd changed it as the virus would inform them of the new one.
The giveaway was, first I have a piece of black tape covering my laptop webcam, and second, I only watch porn via my 55inch TV in another room as a second monitor which doesn't have any web cam. Suffice to say, I didn't hear from them again.
