Vista - Help on how to get rid of speedbit from ie in windows vista

Hi. i had downloaded accelerator installed on my laptop along with speed bit video accelerator and optimizer. I didnt like it and decided to uninstall it all, but somehow its still somewhere in my operating system because whenever i open a new tab in ie8 it says at the bottom of the page that its powered by speedbit. And my tab options such as: view/open recently closed tabs are gone. I have tried changing options in tools tab and add-ons already. I would like to get it back to normal. does anybody have a solution to this?

attach is a screenshot of wat my ie8 tab window looks like.
