How they work
You get a phone call, pop up, or an urgent message from someone saying your computer is infected with a virus. It might seem like the message came from a well-known company, or maybe your internet service provider. The message tells you there are viruses or other malware on your computer. You are urged to call a number or risk losing your personal data.
These are scammers who want to sell you useless services, steal your credit card number, or get access to your computer to install malware, which could compromise all the information on your computer. If you give remote access to these individuals, they will often tell you they are going to give you a refund since the anti-virus software didn’t work. They will ask you to log into your online banking platform so that they can key the refund. They may tell you they accidentally sent you too much money, for example $4,000 instead of $400. They will ask you to purchase gift cards or wire the difference or they will get fired. However, they did not give you a refund, and may have moved your money or made it appear like funds were deposited into your account.
