Do not call 1-888-494-0464 because the telephone number is a fake Technical Support number used by cybercriminals to trick their potential victims into calling it. I got a warning message on my computer where an agent claimed they do genuine Microsoft support, but I knew it was a scam because Microsoft Technical Support doesn't call their customers, the customers call them. The scammers may also claim they are technical support representatives from Yahoo, Amazon, Facebook and other popular tech companies.
Recipients of the fake messages who have called 1-888-494-0464 and given out their banking information are asked to contact their banks for help, change the password of their online accounts, and contact their local authority if they gave out other sensitive information.
