Is there a "More details" option in that window?
If not, what exactly does the window tell you, any information at all?
If you have any Yahoo components added to IE, eg toolbar, I would remove it. You may want to look at IE > Tools > Manage Add-ons, then the "Search providers" options.

At least once a day my vista alerts me to a software change that needs my permission to continue. I cancel the change only to have my internet explorer home page being changed from my preferred Google home page to a Yahoo home page. HELP!
