A **tech scam**, also known as a **tech support scam**, is a type of fraud where scammers pretend to be technical support representatives from well-known technology companies like Microsoft or Apple. They use social engineering tactics to convince victims that their devices are infected with malware or viruses, and then ask for remote access or payment to fix the supposed problems, which are often non-existent. The scammers aim to steal personal and financial information, install malware, or charge exorbitant fees for unnecessary services.
