I'm sorry about the issue. It looks like you accidentally allowed Yahoo to be set up as the home page, or you accidentally installed something related with Yahoo. Please try the following fix:
- In Google Chrome, click on the 3-bar icon at the upper right corner, then click on Settings
, then click on the option "Set pages" on the right
, then move the mouse to the yahoo item, then click on the "x" icon on the right of it (remove anything you see there)
, then click in the box, then type google.com
, then click OK, then check.
Please reply at the box below to continue troubleshooting. Thank you.
