"Critical Threat Detected: Adware App" technical support scam in detail
This deceptive message appears to be a fake "Windows Defender" warning stating that a critical threat has been detected on a computer, specifically an "Adware App." The message implies that access to the computer has been blocked for security reasons and urges users to contact "support" immediately to resolve the issue.
The message provides a phone number (+1-855-339-4500) for "Windows Helpline" and "Windows Support" for users to call. However, this is a scam designed to trick users into contacting a fake support center where they will be asked to pay money for fake services, provide sensitive information, or give access to their computers.
The ultimate goal of technical support scams like this one is to steal personal information (e.g., credit card details, ID card information, or login credentials) or money from victims.
