Mary it looks like something reset IE 10 default search choice, Bing, back to Bing.
If you'd like to set your search to something other than Bing, go to the upper right hand corner in IE 10, click on the icon that looks like a gear, go down to, and click on, Manage Add-Ons. On the left hand side of that window you'll see Search Provider. Left click on that opens another window showing which search providers are available. The ones IE 10 uses as default will show enabled, others not used show disabled. If there's one there you'd like to set as default, left click on it to highlight it, then go to the bottom of that window and look on the left to enable a provider, or on the right to set as default. If the one you'd like to use is disabled, re-enabled it then go to the right and check set as default.
If something gets your goat, it just proves you have a goat to get.
