Updating the AntiVirus Engine and Definitions Manually

Though AntiVirus automatically updates the engine and definitions according to intervals determined by the Polling Frequency, you can perform an immediate update manually from the AntiVirus tab in the Subscription Service Configuration page.

Prerequisites:

  • You must have a valid AntiVirus subscription.
  • Ensure at least one AntiVirus content storage location is set. See Setting an AntiVirus Content Storage Location.
  • Endpoints hosting agents must have a minimum of 1 GB of free disk space for the creation of temporary files during an update.
  1. Select Tools > Subscription Updates.
    The Subscription Updates page opens.
  2. Click the Configure button.
    The Subscription Service Configuration dialog opens.
  3. Select the AntiVirus tab.
    Subscription information and configuration options are displayed.

    4. The date and time the system last checked the Global Subscription Service for engine and definition file updates is displayed in the AntiVirus communication settings section (Last Checked GSS).

  4. In the AntiVirus engine & definition versions (Server) section, click Download now.
    A dialog appears, prompting you to confirm the action.
  5. Click OK.
    The server checks the Storage Location for a new AntiVirus engine and definitions update.

    Information about the update attempt will appear on the Tools > Subscription Service page under the Subscription Service History section as Type AntiVirus / Content (32-bit) and AntiVirus / Content (64-bit).

    Immediately after retrieving an update, the server sends a notification about the file's presence and licensed agents begin to download it: online agents at once, offline agents when they reconnect with the server. Distribution to agents will be postponed if they are part of a group assigned an agent policy set with a definition distribution delay (see Delaying the Distribution of AntiVirus Definition File Updates to Endpoints). If a scan is in-progress on an endpoint, the new definitions file will be used immediately to complete the scan. Files in quarantine will be automatically scanned using the new definitions file.

Network bandwidth usage per endpoint can substantially increase during the engine and definition download.

Tip: DefUpdate.log on endpoints in <INSTALL_DIR>\LMAgent\logs\AV keeps a running record (version number and date/time) of all the definitions files an endpoint installs.
