According to information found on the Internet, it seems that the VO package is malware, and it's advised to completely remove it from your computer. To do this, go to Start > Control Panel > Programs and Features > select the package and click uninstall. By doing this, only the VO package will be removed. If you can't remove it this way, 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. Due to the fact that this might be a malware, it's advised to use AdwCleaner to make sure that there are no leftover rogue registry keys or toolbars in your system.
