A browser's Deceptive Site Ahead warning indicates that the user's requested website may contain malicious or phishing content or otherwise be insecure. This precaution allows users to avoid visiting potentially harmful websites online. Popular browsers like Chrome, Firefox, and others have the ability to automatically detect unsafe websites turned on. Such websites frequently advertise software that many security programs have identified as potentially unwanted, as well as infamous spyware/malware programs, misleading software bundles, and websites that imitate other well-known websites. Additionally, a secure website that has recently been breached by hackers or doesn't have the proper security configurations may cause such a warning to appear.
