Help!!!

[sgorny]

My PC's browser has been hijacked. I run Windows XP Pro, and use Internet Explorer. When I try to go to any site, it switched to dw.dailywinners.com (don't go there) - and tries repeatedly to access it. Clicks until I hit the stop button. It won't let me go anywhere else, no matter what I type in. I cleared my cookies, my cache, my history... I ran Ad-Aware & Norton AntiVirus. And still, my PC can't log onto the internet (or it tries to, but just that damn dailywinners site). Which I listed as a restricted site, so it won't log on.

Any help or advice would be greatly appreciated.
