FlyDigital scam?
My husband clicked on an email he says caused his iMac to freeze. Message popped up saying "You've been hacked" w/phone # to call. He's new to Mac and I wasn't around so he called (not sure of the number). They told him because his Mac was 5 years old its "security software" was no longer under warranty and he needed to download something that cost $250. He gave his credit card # to someone who claimed to be a subcontractor for Apple and received an invoice headed "FlyDigital" and he thinks he downloaded something called Team Viewer, but he's not sure. Of course the email has disappeared. His iMac is from 2010 running Yosemite (10.10.4).
It sounds like a massive scam to me, and putting aside the issue of "what was he thinking", has anyone heard of anything like this before? Any ideas on how to tell if it's legit?
