A technical support scam is an illegal activity when a fraudster tells you that he is offering a legitimate technical support service, which frequently occurs by way of an unexpected phone call.
Fraudsters make an attempt to trap victims by giving them remote access. These fraudsters also abuse the trust of the victims and force them to pay for credit card services. If you receive an unexpected phone call from someone telling you that there is a problem, hang up and do not call back.
Be assertive and hang up immediately!
