The SMSMSE Administration Console shows a virus definitions date that is older than one or two days.

To view the virus definition date used by SMSMSE perform the following steps:

1. Open the SMSMSE Administration Console.

2. On the Home tab the label Virus Definition Date is the date of the virus definitions used by SMSMSE

The  most common reasons that the virus definitions are out of date are:

1.      SMSMSE version is older than 6.5.7

With older versions, if two different processes attempt to do virus definition copy at the same time they cause interference. The copy process does not succeed.

2.      Symantec Endpoint Protection 12 Beta is installed

SEP 12 beta uses a specific LiveUpdate server.  This LiveUpdate server only contains virus definitions for SEP 12 and no other product does not           contain the SMSMSE virus definition files

3.      Symantec Mail Security for Microsoft Exchange is not registered correctly with LiveUpdate server

When the user's AppData setting is not correct, errors are reported while installing SMSMSE or registering with LiveUpdate. LiveUpdate server will      also report errors.

4.      LiveUpdate reports errors in Log.LiveUpdate

LiveUpdate configuration or settings may not be correct. The logon account for Live Update in services should be set to Local System account or proxy settings for LiveUpdate may not correct.  LiveUpdate reports errors in Log.LiveUpdate.

Solution

1.       Upgrade to SMSMSE 6.5.7 or later.

See the following article for details:

Symantec Mail Security for Exchange (SMSMSE) continuously reports Windows application event ID 25 "Updated Virus Definitions" and is not using current virus definitions when multiple copy processes occur at the same time   

2.      Uninstall SEP 12 beta.  Then install the most recent production version of SEP

See the following article for details:

Virus definitions are not up to date for Symantec Mail Security for Microsoft Exchange (SMSMSE) when Symantec Endpoint Protection 12 Beta is installed    

3.      Change the AppData setting for the user and re-install or re-register SMSMSE

See the following article for details:

LiveUpdate is not working and virus definitions do not update when registry AppData location is incorrect                       

4.      LiveUpdate reports errors in Log.LiveUpdate
