Google’s Safe Browsing Advisory

We want our users to feel safe when they search the web, and we’re continuously working to identify dangerous pages and to increase protection for our users. Google uses automatic algorithms and user feedback to compile lists of sites that may be dangerous.

The two major types of dangerous pages on our lists are phishing pages and malware pages.

The lists of potentially dangerous pages are available to developers via the Safe Browsing API. These lists can’t perfectly protect users from every risky site on the web, and there is always a chance that a safe site could be misidentified as risky, but we update the lists regularly to keep them as current as possible.


Phishing, or spoofing, is a type of attack in which a page asks you for your personal or financial information under false pretences. To learn more about phishing, you can visit Antiphishing.org.


Malware is a type of software that attempts to steal your personal information or use your computer to do things that you do not intend. Malware pages are web pages containing malicious code that could be downloaded and installed on your computer without your consent. You can learn more about harmful web content including viruses and other malicious software and how to protect your computer at StopBadware.org.
