Oh, those screenshots take me back to when I first encountered this type of threat. They were the most fun to clean off of client computers.
A poor client said he suckered into this scam and entered his credit card to buy it. No clue if he ever got his money back or if he was a victim of id theft.
I think I even got one of those on one of my computers years ago. I think I had opened a website that was hacked.
Back then, I manually cleaned the malware off. Now, I use Malwarebytes.
