Most common mistake ppl make when uninstalling the sponsorprogram is they dont have their internetbrowser fully closed (from taskbar an systray also). Next mistake is to run ad/spyware removals before uninstalling...this will criple the uninstaller, so you'll have to reinstall with sponsor first before uninstalling. I don't know wich one it is in your case, but i hope i gave you a clue
