Download these two programs. Superantispyware and Malwarebytes. Both are free. Once you download them make sure you update them and then run a complete scan. Only run one at a time, and after it finishes removing the threats reboot your computer and then run the other program to see if it finds anything else.
Also when running these I reccomend running them in Safe Mode. To get into Safe Mode usually you just have to tap the "F8" key as soon as your computer starts booting up. It'll then bring you to another screen once you're there select "Safe Mode With Networking". Your computer will boot into Windows with the bare minimum of services and processes running. Run your scans from there and then reboot when they're finished.
You can do a google search for these programs and it'll bring you to the download pages or you can follow the links below.
