How to Reset Google Chrome
If your Google Chrome Web browser suddenly has an unwanted toolbar, its home page has changed without your permission or your search results appear in a search engine you never chose, it may be time to hit the browser reset button.
Many legitimate pieces of software, especially freeware, slap on third-party, browser-hijacking extensions when you install them. The easiest fix is a full browser reset.

1. Click the icon that looks like three stacked lines at the top right of the browser window.
2. Select 'Settings' in the drop-down menu.
3. Click on 'Show advanced settings' at the bottom of the Web page.
4. Select 'Reset browser settings' at the bottom of the page.
5. Select 'Reset' in the confirmation pop-up window.
