Hey man. I had the same thing and this is how you get rid of it.
First download this file to your desktop.
http://siri.urz.free.fr/Fix/SmitfraudFix.exe <-- Safe to download
Nest, open up internet options in control panel. Delete all temporary internet files, cookies etc. Clean the sumbitch up.
Next reboot machine and at POST screen hit the F8 key and boot into safe mode. Run the program you downloaded above. When it asks if you want to clean the registry too, say yes.
Reboot computer, fixed. Let me know if it work out for you. It should.
