It's a bit of a long shot, but if you go to start > run > msconfig > startup and see if you can find that program listed there, if so uncheck it. Also, where did you get this wink? Only download them from sites that you trust, or just avoid them altogether. I'd also check what sites you've downloaded from in the last few days. Finally, if none of that helps, you may have to re-format your hard drive, that is a last resort, and should only be done after you've backed-up all of your important files, as it will completely erase your hard drive, that solves your problem, but is a rather less-then-optimal solution.

Now that I think about it, what browser do you use? If it's Firefox I'd be very interested to know more about this program that alters your Firefox settings, if it's IE you may want to switch, just because other browsers are far more secure.
