That's not part of Windows 10. You must have accidentally installed that while installing something else. It's actually malware and you should remove it.
Go to Control Panel. Click on “Uninstall a program” option under the “Programs” category. Find Web Discover and uninstall it.
Then I'd highly recommend downloading
Malwarebytes Anti-Malware, and doing a system scan to make sure you don't have any other nasties.
