Apple or Windows Support...If your computer freezes and you get a call from 'Apple Support' (or 'Windows Support', I suppose)
If your computer freezes and you get a call from "Apple Support" (or "Windows Support", I suppose), which will then put you in touch with the "Security Section" of your bank, HANG UP! and then turn off your computer and reboot. Problem solved. No tech support will ever make an unasked for call to you. The "Apple Support" is fake. So is the "Security" of your bank. If you're uneasy, call your bank! Do NOT listen to their instructions about telling nobody. This is for their security, not yours.
You can get scammed out of a lot of money if you follow their instructions.
