If BurrWalnut's suggestion doesn't help...
One of the most thorough ways to determine if your PC is still infected with anything is to run HijackThis (HT) click here. Then post the resultant log in a dedicated HT forum like click here (instructions before posting click here). They may ask you to run other free programs as well.
You can also do a quick DIY HT analysis via click here. Do NOT manually remove anything 'suspect' on your own, but rather ask for help on one of those forums. All the best with it. G
