Looks like a bad day. Have you tried a system restore to before this happended?
I would also suggest that you might consider, downloading malwarebytes onto a flash, then starting your computer in safe mode, then running the malwarebytes progam to see if it finds anything wierd. Its a real easy one to use, and it catches quite a bit. there are other options as well.
Also would recommend, entering your internet options, and selecting lan settings, and then disableing a proxy server if you havent set one up.
