Because Microsoft Windows allows you to block malicious or dangerous websites to protect your computer and personal information, if you can't access a website using Google Chrome, it might be blocked. Unblocking a website takes just a few seconds; however, keep in mind that the website in question might indeed be dangerous and may harm your computer or data. If you can't find the website in the Restricted Sites list, it may be blocked from the Hosts file.

Unblock a Website From the Restricted Sites List

Step 1

Launch Google Chrome, click the Chrome menu button -- marked with three horizontal lines -- and then choose "Settings" from the menu to open the Settings page.

Step 2

Click the "Show advanced settings..." link, and then click the "Change proxy settings..." button in the Network section.

Step 3

Click the "Security" tab, select the "Restricted sites" zone, and then click the "Sites" button to open the Restricted Sites window.

Step 4

Select the blocked website from the Websites list, and then click the "Remove" button to unblock it. Click "Close" to close the Restricted Sites window, and then click "OK" to close the Internet Properties window.
