Pheo you installed anything recently? ... oftenly if you install or visit pages with malicious script this happens.
easiest way to fix it is to go into
Tool//Internet Options//[Programs]//>Reset Web Settings<
it should return your settings back to default Microsoft; then all you need to do is change the homepage again and apply
also
Tool//Internet Options//[Advanced]//>Restore Defaults<
should also disable the scripts that are causing the problems...
this is why i tend to use Mozilla when i visit sites that aren't certificated, Explorer doesn't catch malicious scripts often and i don't care if Mozilla gets screwed up
