Hi Karen, if you can't uninstall Web Protect using Control Panel, you could try using third party tools:

CCleaner
Download, install and run CCleaner. After launching the program select "Tools". In the uninstall programs list select the program you want to uninstall and click the "Run Uninstaller" button.

Revo Uninstaller
Download, install and run Revo Uninstaller. After launching the program select the program you want to uninstall from the list and click on the "uninstall" button.

IObit uninstaller
Download, install and run IObit Uninstaller. After launching the program select the program you want to uninstall from the list and click on the "uninstall" button.

PS. I usually use Revo Uninstaller. After uninstalling this adware be sure to scan your computer with Malwarebytes Antimalware and Spyhunter. There's a good chance that Web Protect wasn't the only adware which infiltrated your computer.
