    Nava shield is a rougue antispyware, which will create unwanted pop ups and mis lead you to buy that application.
    Most of the antivirus like Avast, Norton, Mcafee arre able to remove its source file and at the same time they are failed to remove the unwanted registry entries created by the infection. Once its source file is removed by the antivirus, the registry entries started to disable all the executables (applications or softwares) installed on your computer.

    In this scenario, we have to remove the registry entries manually.
