If I download and upgrade to IE8, why does it still ask me if I want to upgrade to IE8?

at the top of my homepage it has the option to "Upgrade to Safer IE8" and I have done this at least 5 times already.|||It is simply an advertisement banner on a web page, it is not a notification from your computer. Everyone who visits that web page will see that banner.|||That is part of the webpage. It doesn't differentiate which version if IE you are using. The same thing happens to me, too.
