In order to remove Search Redirect completely you will need to reset Chrome back to its initial settings.
If you are unsure what extension may be causing this redirect, you should perform a scan using the steps in the removal guide below. On the other hand, if you do not wish to have your searches redirected, then you can just remove the extension. If you know the extension that is causing the redirect and you do not mind it then there is nothing you need to do.
If your browser starts redirecting your searches to, then you have an extension that is redirecting your searches installed. These browser extensions perform the redirects in order to track your searches or to generate revenue from advertising. Your address bar searches are redirecting through because you have a browser extension or addon that is performing the redirect. While redirecting, your browser may show the 'Connecting to ', 'Waiting for ', or 'Transferring from ' messages in the status bar.
