iObit Uninstaller is a software removal tool that can be used instead of Windows's built-in feature Add/Remove Programs. It basically has the same function but it can also scan your system for remnants, hunting for both leftover files and registry keys. You can then review and remove them as you wish. It also comes with a browser plugin removal tool, but it is not so efficient as it doesn't show what plugins are installed in what browser. For more information and latest version download you should access iObit Uninstaller's website.
