As per my explore in the Internet it causes because of viruses. When I tried to uninstall this VO Package and end up with  this warning This program is blocked by group policy. I used the  software Revo  uninstaller, it could not finish the job of uninstallation but let me to clean the files and registry entries. That’s good.

After that I used malwarebyte – to clean the computer and got Windows 7 is free from viruses.
