How do I get rid of the "upgrade to Safer IE8" when MY IE8 is a more current version?

Every time I open my yahoo friendly browser, I get prompted to download the New IE8. When I do, it tells me not to install because my version is newer than the one it keeps prompting me with. How do I stop this??!!!! It's a viscious circle.|||ignor yahoo, they want you to install there version as it has adware and spyware in it for them.
