SPY WARE, OMG!!!!! It's ok I'm here for you. If you don't know by now you should that Microsoft has a free beta of their spy-ware removing software. It is currently the best spy-ware, ad-ware, mal-ware, worm and trojan removing software out there. It updates itself and runs a system check every morning at 2am by default. This will find the spy-ware that's embedded in your computer in all the dlls and delete it.
Get it from Microsoft here.
