  1. Overview of this Critical Patch Release
  ======================================================================
     This critical patch resolves the following issue:

     Issue:    The current version of the Advanced Threat Scan Engine 
               (ATSE) in IMSVA 8.2 may not be able to recognize macro 
               virus.
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Solution: This critical patch updates the ATSE in IMSVA 8.2 to 
               enable it to recognize macro virus.
               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
     Procedure: To enable the solution:

                a. Upgrade the ATSE engine to version 9.826.1078 or any 
                   later version.
                
                b. Install this critical patch (see "Installation").

                c. Connect to the IMSVA database using the following 
                   command:
                
                   /opt/trend/imss/PostgreSQL/bin/psql imss sa

                d. Run the following SQL statement to set the ATSE 
                   aggressive level to 4:

                   update tb_global_setting set value = '4' 
                    where name = 'detection_aggressive_level';

                   Note: The default value of this key is "3" which
                         disables the mechanism.

                e. Log off from the server by running the following
                   command:
                
                   \q

                f. Restart the scanner service using the following
                   command:

                   /opt/trend/imss/script/S99IMSS restart
