Brower hijacked with redirect to a commercial site or link portal

I can't click on a link in a search engine without being redirected to a commercial site or link portal  that was vaguely related to my search (most of the sites are just a short list of links). I ran Norton Internet Security 2009 and Ad-aware, but both found nothing. I know that there was already a thread for this topic, but the reply button was greyed out. I ran HijackThis, would someone be willing to look at the log file?
