My search engines are showing up in German

I don’t know what I did but whenever I use Live Search or Google they either show up in German or give me German results. I’m currently using Windows Vista Business SP 1 and Internet Explorer 8 Beta 2. I’ve ran an antivirus search but came up nothing. I’m not sure if I’m missing an option somewhere. I’ve tried the Language option in IE and my OS language is ok. It’s only when I go on certain websites in IE. I’m this close to uninstalling IE 8, go back to IE 7 and see if that fixes the problem.
