Forget e-mail. Criminals are making old-fashioned phone calls and offering free security scans in order to gain access to people’s computers, according to Microsoft.
To run the con, criminals pretend to be PC security experts from legitimate companies. They call their intended victims, warning of a risky security threat and offering to run a free security checkup. If the victims take the bait, the scammers gain access to their PCs and often capture passwords or financial information.
