Google has recently announced that it will enable Safe Browsing by default on Chrome for Android, starting with Chrome version 46. Google noted that this step would protect Chrome users on Android from certain types of malware, unwanted software, phishing attacks, and other cybersecurity threats. It should also be noted that this feature would also be available for Chrome users on iOS devices, but not as default.
In practice, Google's Safe Browsing systems will now block by default Android Chrome users from navigating to sites that were flagged as hosting or encouraging the download of unwanted software, phishing, social engineering and malware, through Chrome's "Red Warning".
It is also important to note that Google is releasing the Safe Browsing feature as part of Google Play Services (starting with version 8.1), meaning that it is expected that it will come to other in- house mobile apps and services in the future.
