Guys, I think there's some confusion here as to QV security basics. Sathish, I recommend you read the Qvs Reference Manual, which should help you. But in answer to your question, to remove an application from all users in the AP, the easiest way is to just move it to a different folder. Alternatively, you can remove NTFS Read (and higher of course) permissions for everyone, but that's a pain. To hide the application from only certain users, remove those users' Read (and higher) permissions. It's that simple: QVS will read the NTFS permissions and only display the applications to authorized users.
Keep in mind that if you're using Publisher and distributing, the distributed file permissions will not inherit from the parent folder so be careful.
Regards,
