This was a toolbar application used to provide methods to convert files between various audio and video formats. However, nowadays the toolbar has been discontinued and it isn't used anymore. To remove it, use 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.
