You have a computer on which you installed Symantec Mail Security for Microsoft Exchange 5.x or 6.x and Symantec AntiVirus Corporate Edition (SAV) or Symantec Endpoint Protection (SEP). You need to know how to configure LiveUpdate.
Symantec Mail Security for Microsoft Exchange (SMSMSE) will share virus definitions with Symantec Antivirus Corporate Edition (SAV-CE) or Symantec Endpoint Protection (SEP) 11 under the following circumstances:
SMSMSE 6.0.8 or earlier on any platform.
SMSMSE 6.0.9 and later on 32 bit platforms.
SMSMSE does not share definitions with SAV-CE/SEP in the following circumstances:
Any version of SMSMSE with SEP 12
SMSMSE 6.0.9 and later installed to a 64 bit system
If your server meets the conditions for sharing, you should disable automatic virus definition updates in SMSMSE and allow SAV-CE/SEP to retrieve the updates.
To disable SMSMSE from performing automatic definition updates
In the left pane of the SMSMSE console, click Admin.
In the middle pane, click LiveUpdate/Rapid Release Schedule.
In the right pane, uncheck "Enable automatic virus definitions updates."
