An agent for Symantec Endpoint Protection Small Business Edition (SEP SBE) cloud displays outdated virus definitions, and is not receiving the latest definitions.


This issue occurs when the virus definitions on the agent computer have become corrupted.


Verify network connectivity

  1. Open a command prompt. Click Start > Run, type cmd, and click OK.
  2. Type ping and press Enter.

If this command results in either a network time-out or a failure to resolve the address, communication is being blocked between your network and Symantec servers.

If you have firewalls or proxies in your network environment, whitelist the required URLs.

Replace old definitions

  1. Download the Intelligent Updater file that is appropriate for your operating system:
    For Workstations
    For Servers

    Note: To confirm the computer's OS architecture, click Start, right-click Computer, and then click Properties. Under System, look for the System type.
  2. Right-click the downloaded file and choose Run as administrator.
  3. When prompted to deploy all updates from this updater, click Yes.
  4. Monitor the agent over the next 24 to 48 hours to ensure that the definitions are updating consistently.

If definitions still do not update after performing these steps, contact us for further assistance.
