Are you sure its not part of that site? Odd that it appears only when you go there, still after system restore.
Using IE8.
I was browsing a website which has articles/photos that allow you to "drag" the article/photo to share with others. Now everytime I go to that website that darn toolbar appears at the bottom just above my taskbar. How do I COMPLETELY get rid of that toolbar (which consists of options to share with facebook, twitter, etc? I did a system restore but it still appears when I go to that website.
