215-398-6745 is active today, 8:22pm EST. Number is listed in Microfost Rats, but I think deserves attention. Active since this winter. Maybe needs a bit of attention. They phoned one of my burners and left a message.
They are classic pop-up screen scammer - but they claim it’s the scammers who put the screen up, not them. They want you to buy warranty, anti-virus, etc - they’ll take a credit card or send you a credit card payment form.
