  1. Critical Patch Release Information
  ======================================================================

     1.1 Issues
     ===================================================================
     This Critical Patch resolves the following issue:

     Issue 1:    When starting the OfficeScan agent with POP3 email
                 scanning enabled, the Real-time Scan (Ntrtscan.exe)
                 service may not be able to start due to a timing
                 conflict with the OfficeScan Listener (TmListen.exe)
                 service.
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 1: This critical patch resolves the timing conflict by
                 ensuring that the OfficeScan Listener service allows
                 the RealTime Scan service to start before starting
                 other services.
                 =======================================================
     Issue 2:    Under some situation, part of scanning process may hang
                 and OfficeScan client may not be able to perform any
                 action on the detected malware. When this happens,
                 OfficeScan does not display a pop-up warning or
                 generate a detection log.
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 2: This critical patch enables OfficeScan clients to
                 perform the required action on malware detected under
                 the scenario described above.
                 =======================================================
     Issue 3:    OfficeScan clients start firewall service improperly
                 on the Microsoft(TM) Windows(TM) 8 and Windows Server
                 2012 platforms.
                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution 3: This critical patch updates the OfficeScan client files
                 to ensure that clients correctly start firewall service.
