You might not need to do something as drastic as reinstalling your OS. First, I'd suggest downloading and running
Lavasoft's Ad-Aware SE as moogie suggested. If that doesn't fix the problem (it probably won't, considering everything you've done already, but it's still a good idea), then download
HijackThis. As the name implies, it's a program that detects and removes hijacks (among other things). A word of warning, though:
HijackThis can be harmful for your system if you don't know what you're doing! The good news is, you don't need to know what you're doing as long as someone else who does is helping you.
Now, once you have HijackThis installed, run the program and start a scan. When the scan finishes, save the log and post the results here.
Warning: Do not — I repeat, DO NOT! — fix anything. You could damage your software or even your OS beyond repair if your remove the wrong thing. Just scan and save the log as instructed. Post the log here and I'll take a look at the results and see if there's anything amiss.
Hope that helps! =^^=
