Well the best thing to do IS indeed downloading spyware removal programs....they know what theyre doin a lot better than you do.
It does make sense to download software to get rid of software because once you are done with the spyware REMOVAL program, you can uninstall it. People use anti virus dont they? Thats software to get rid of software.
Anyways, there are many ACCREDITED spyware removal programs that will get this done that certainly do not contain spyware.
Here are two sites that you should go to. Please download both products and run the scans. After they are done feel free to uninstall both.

Then, AFTER YOU DO WHAT I SAID ABOVE, you might want to try hijackthis...this will create a log that we can look at here to make sure everything is okay. Copy and paste the log and we will look through it and tell you what to delete.
