RaposaNegra

Well my problem is this, when I type like "www.s" in I.E it shows a drop down like this: I don't want this to appear. I've alreadu used CCleaner lots of times.. I've rebooted the computer and runned it again and it didn't fix my problem. Sorry but it's in PORTUGUESE, but as you can see I have all options selected... Can someone help me please?
