If object integrity is the issue, do not change the QVFYOBJRST system value

or perform other actions that might allow the questionable object to restore.

Doing so can circumvent the security that signature verification provides

and allow a harmful object onto your system. Instead, you need to contact

|
the object signer to determine the appropriate action to take to resolve the

problem. </td>
