Well if you were using linux you wouldn't get viruses. Linux doesn't get viruses. So there's that.
All I can say is, the only way to be sure to cure your windows installation is to format and reinstall it. Otherwise there's no way to be sure that there isn't some stuff still hiding there somewhere. Just backup whatever data you have on an external drive (don't use the infected OS for this, otherwise the virus may just spread on the external drive) and wipe out your windows partition, then re-install it.
Maybe you did... but you can never be sure. A format + reinstall is the only 100% sure way to cure a malware infection on windows. Remember, you can't trust AV software. They only find things they know how to find, and report more false positives than real ones.
Of course, you might be satisfied with being less than 100% sure, that's ok if you don't do anything really important where security matters a lot on your computer.
