How do I get those annoying estee lauder ads off my computer?

I can't read an article or send an email without those horrible ads getting in the way. I used to buy estee lauder products, but never again!|||Most of the ads are cursor activated, just wave your cursor over it once and it will go back into place. The ads pay Yahoo's bills so if we don't want them, then subscribing to Yahoo Mail Plus is the way to go. No ads.
