The outstanding growing number of computers per household all over the world has offered scammers a variety of fraud ideas.
One of the latest telephone scams reveals criminals calling every house number they can, claiming to be Microsoft technicians offering “free security checks”. Once they get the victims’ trust to get them logging into their computers, the scammers get either remote access to the machines or trick them to give away the credit card number.
According to a survey done by Microsoft, 16% of their product users have received such phone calls. You can get one too, not necessarily from “Microsoft techies”, but from fake Apple, Samsung, Google reps, etc.
How to avoid: these companies are so busy already offering tech support - it’s probably impossible for them to call you, instead of the other way around.
