How to get rid of ceraitn ads on facebook?

[Jfacleon]

It all started when idiot me decided to "win" a 25 dollar apple gift card. They said i had to do some surveys or sign up for pagerage. When I did, the toolbar downloaded itself, and I got it uninstalled. But when I get on facebook, some ads that are not normal will pop up like in the middle of the page. Theyre the ones like "someones looking for you! give us info and see!" How do I get rid of these?
I tried to delete them, I went to options but there was no "delete cookies" option, and I even went to the page were it deleted all history, cookies, passwords, etc, but they're still not gone.
