Open the Control Panel, then "Internet Options", then select the "Advanced" tab. Once there, click on the "Reset" button and select OK/Yes, when it asks "Are your sure?".

Resetting Internet Explorer will eliminate some of the various add-ons that may have attached itself over time. If you visit a website later, that needs one of those add-ons, you can choose to allow or disallow it.

Hope this helps.
