The application features its own uninstaller. This means you can use Add or Remove programs to remove it from your computer. If you have problems doing this, try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
After that, try running AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
