jqsnotifier.exe, ssvagent.exe, jusched.exe and jbroker.exe are not signed in b08.

Users were asked to Allow/Deny many a times opening an Application. Opening a Firefox throws Security Warning saying jqsnotifier.exe from Unknow Publisher. IE throws Security Warning for ssvagent.exe - Unknown Publisher.
Since jbroker is not signed ( ?) Allow /Deny dialog appears many a times while loading any application on Vista.
