My friend recently got a popup and she allowed the scammers access to her computer. She eventually turned the computer off so that they didn’t do any damage, but they called her back using a different number than she called with. Here’s the numbers.
She lost the URL though, so I couldn’t get a hold of that.
Original popup number: 888-691-4111
Number that the scammers used to call back: 855-532-9333
