I was on a new website and when I went back to Yahoo! I noticed an icon/link to the website on my Yahoo! toolbar. How do I get rid of it and prevent others from attaching automatically like this one did?

I downloaded the Yahoo toolbar specifically so I would bet an email alert. I noticed that some of the buttons are not present even after a successful download. I want to remove other buttons but it is not clear on how to accomplish this. Help!

I re-downlaoded yahoo toolbar, downloaded yahoo anyi spy and icon wont appear to use it. I looked at my computer programs in the uninstal program and I see it’s on my computer. How to I get to be able to use it? Icon just wont add to toolbar…I tried everything, including toolbar button home and hit add and icon will not appear or be able to be used??
