OfficeScan agents that update components from the OfficeScan server or a customized update source can use the following update methods:
Automatic updates: Agent update runs automatically when certain events occur or based on a schedule. For details, see OfficeScan Agent Automatic Updates.
Manual updates: When an update is critical, use manual update to immediately notify agents to perform component update. For details, see OfficeScan Agent Manual Updates.
Privilege-based updates: Users with update privileges have greater control over how the OfficeScan agent on their computers gets updated. For details, see Configuring Update Privileges and Other Settings.
