How to manually update the Virus and Spyware definitions content included with Symantec Endpoint Protection (SEP) 12.1 client installation packages exported from the Symantec Endpoint Protection Manager (SEPM).
This procedure requires an exported client package for the version of Windows you are installing to. If you are installing to both 32-bit and 64-bit Windows computers, you will need exported client installation packages for both the 32-bit and 64-bit version of the SEP client. This procedure does not work with single .exe file installation packages.
You will also need copies of the latest Virus and Spyware definitions content from your Symantec Endpoint Protection Manager (SEPM).
