Internet 2 min read

The “Deceptive site ahead” security error message in Google Chrome is a security protocol that blocks you from landing on deceptive websites. Google explains that deceptive websites may trick you into doing something dangerous like installing software or revealing your personal information (for example, passwords, phone numbers, or credit cards). A “Deceptive site ahead” security error may also be produced if your browser attempts to redirect to websites known for online scams, including tech support scams and advance-fee fraud.

When a “Deceptive site ahead” security error occurs a user will be directed to a red webpage that says:
