“Safe Browsing” is on by default in Google Chrome, which means that your browser will stop you from visiting websites that are known to inject malware, steal passwords, or otherwise compromise your security.
You can customize Safe Browsing in your Chrome browser settings, under “Privacy and security. “Standard protection” is the default described above, while “Enhanced protection” will give you faster, more proactive protection and warn you about password breaches, but at the expense of sending more data to Google. “No protection” is also an option, but is not recommended.
