How to find a product key

I downloaded some sketchy software and it started downloading random apps all over the place on my computer. I tried a reboot, and now my computer is asking for my product key. I tried clicking the X and cancel buttons but they won't work. I have a iPod though. Is there a website or app where I can see what my product key is on my iPod? Any solution that doesn't involve calling Microsoft or spending money works for me really.
