Yup, you're hijacked. You need to post a log in our Hijackthis! forum
. Read this
first. Do not reply to your own log because the helpers are looking for posts with zero replies. Do not try to fix anything with Hijack yourself. Hijack reports things that are normal as well as things that are malware and you can quickly hose your computer.
Please be patient, they're working as fast as they can.
