Symantec endpoint protection definitions not updating
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 publish Symantec Endpoint Protection security content with the date 12/31/2009, and will only increase the revision number of the content.More specifically the last certified definitions that was published on December 31, 2009 was “12/31/2009 rev. The next certified definitions to be published will have a revision number greater than 041.As of Thursday January 7, 2010; the Symantec Endpoint Protection Antivirus definition version "12/31/2009 rev. Rev 119 includes all of the latest definition updates through January 7, 2010.If the virus definitions of your Norton are out of date, you can use Intelligent Updater to update it.I'm keeping tabs on a remote sever that is running Symantec Anti Virus Corporate Server 10.1.7.7001.Any content with a date of 1/1/ AM or newer will be purged from the SEPM if the maximum number of definitions revisions has been reached.
Since 12/31/09 rev xxx is considered the latest content available to the SEPM, a client will not update to a content revision later than the highest numbered revision available on this date.
Definition builds for all other products remain the same.
To correct the definition date showing on SEP 11.0.x and SEP 12.0 SBE clients, customers can configure clients to download the latest ‘Virus and Spyware Protection’ definitions directly from Live Update.
The latest ‘Proactive Threat Protection’ and ‘Network Threat Protection’ definitions were released in December 2009, and therefore will not show a January 2010 date.
Once a client has downloaded January 2010 definitions from Live Update, the client should remain configured to download content from Live Update until your servers have been patched with a fix for this issue.
Below is an excerpt from the Symantec Antivirus knowledgebase, Symantec antivirus, although it updates the same as before, doesn't recognize a date newer than 2009.
