Update OfficeScan agent components manually when OfficeScan agent components are severely out-of-date and whenever there is an outbreak. OfficeScan agent components become severely out-of-date when the OfficeScan agent is unable to update components from the update source for an extended period of time.
In addition to components, OfficeScan agents also receive updated configuration files automatically during manual update. OfficeScan agents need the configuration files to apply new settings. Each time you modify OfficeScan settings through the web console, the configuration files change.
In addition to initiating manual updates, you can grant users the privilege to run manual updates (also called Update Now on OfficeScan agent endpoints). For details, see Configuring Update Privileges and Other Settings.
