Last year the “FBI” demanded money & froze my screen. I took it to Geek Squad at Best Buy (the contract pays for itself) and they said, “been seeing this one for a month now” & cleaned it out.
So, it's pay the scammer or pay the Geeks? Think maybe it might be a Geek creation, then? I've long suspected that virus programs are created by those who sell the virus protection and cures!
And if they are caught, execution is too good for them.
