|What software have you tried to remove the Trojan so far? When I had a redirect virus, I managed to get rid of it with Spybot Search And Destroy. They seem to be getting more sophisticated though!|
Also, are you getting the problem on all browsers that you use? I had a weird case where it was only redirecting Internet Explorer. Firefox and Safari were fine. Another reason I hate IE.
I'd say try Spybot first, see if that does anything.
