Below is an excerpt from the Symantec Antivirus knowledgebase, http: This seems like a Y2K problem, only it's Symantec antivirus, although it updates the same as before, doesn't recognize a date newer than Symantec Endpoint Protection v This issue can manifest in the following ways: The following is a list of the expected behaviors of affected Symantec software with default configurations. If the settings for functionality such as alerts or notifications have been altered from the default values, it is possible that your experiences may vary from those below.
End users of managed clients will not receive an alert notification by default The default for this alert is 30 days SNAC Clients: This issue does not directly impact this component Live Update Admin Server: This issue does not directly impact this component. IU definitions will display a normal version date and are not directly impacted by this issue. To mitigate this issue, Security Response is no longer incrementing the date on SEP Security Content and instead only incrementing the revision number of the content.
Security Response will continue to provide definitions in this manner as a work around until a permanent solution can be provided. Symantec is aware of this issue and is currently investigating it. This document will be updated as soon as more information becomes available. The next certified definitions to be published will have a revision number greater than Rev includes all of the latest definition updates through January 7, Relative definition age can be determined by the revision number.
While this issue is being resolved SEP definitions are being built outside of the normal build process. To ensure we retain the quality of the definitions during this period the SEP definitions are only being built once a day. Definition builds for all other products remain the same. Client machines will continue to receive the latest protection available without any intervention from the user. Please be aware of the following exceptions: Until This issue is permanently resolved, HI policies should be modified to relax minimum Antivirus Signature File age requirements.
Configure clients to download content from Symantec LiveUpdate Note: Enabling client LiveUpdate may cause an increase in network traffic as each client connects to the internet to download virus definitions. To correct the definition date showing on SEP These definitions are properly dated as definitions. Once a client has downloaded January definitions from LiveUpdate, the client should remain configured to download content from LiveUpdate until your servers have been patched with a fix for this issue.
Once patches are available and this temporary problem has been corrected by Symantec, details will be posted to this KB article. Please also note that once the SEPM servers have been patched, the clients should remain configured to download content LiveUpdate for at least 3 days to ensure that they will get delta definitions from the SEPM server.
