To uninstall this product you can try the classical way from Control Panel. To do this, go to Start -> Control Panel -> Add/Remove Programs (Windows XP) or Programs and Features (Windows 7) select the software and click Uninstall. If this doesn't work, you can use a third party tool like Revo Uninstaller to wipe out all traces of its presence from the system. After this, try using AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
