The title of the thread.
If you're still looking for anti-spyware, the one you've already got, SuperAntispyware, is excellent. I have the free version too. Upgrading to the paid might be a good idea. Otherwise, Malwarebytes, as mentioned above too, is another good one. I have the paid version of that on my own PC.
For anti-virus, Microsoft Security Essentials is free and excellent.
