OfficeScan clients that
               update components from the 
OfficeScan server
               or a customized update source can use the following update methods:
            
 
            
               - 
                  
               
 
               - 
                  
Manual client updates: When an update is critical,
                     use manual update to immediately notify 
clients to perform
                     component update. For details, see
