Glad that you somehow managed to achieve what you were looking to but in the future be aware when you install something from the internet of the ask toolbar. free/shareware is quite stealthy and with a barely noticeable request (since we tend to click so quickly through) sneak extra Sugar like that onto your system. I've fallen victim before myself. I've actually been told the ask toolbar isn't safe. Most of that extra stuff probably isn't.
That might have been what happened to you, it might not have been. Since you seem to have no notion of what you did to solve the problem perhaps you should check your extensions to see if the ask toolbar there but since I don't know what browser you are using so I can't give you instructions.
