Oh, your homepage is changed to yahoo.com? If so just click Tools, then internet options then change the default homepage and click ok.Yahoo is not a program...it's a Start Page.
Change the start page to what you want.

NOTE: Yahoo uses IE as it's Browser...if you are unhappy with it use FireFox or another browser.You should just use FireFox anyway because it is better by default.
