How to update Symantec AntiVirus Corporate Edition definitions without using LiveUpdate

Question/Issue:
Your primary Symantec AntiVirus Corporate Edition server cannot automatically download virus definitions using LiveUpdate.

Solution:
Download navup8.exe and *.xdb files into the location on the Primary Server., and then run navup8.exe to update virus definition. :

The default location on the Primary Server depends on the version of Symantec AntiVirus:

• Symantec AntiVirus Corporate Edition 8.x:
  C:\Program Files\SAV
• Symantec AntiVirus Corporate Edition 9.x:
  C:\Program Files\Symantec AntiVirus

Source:
navup8.exe: ftp://ftp.symantec.com/AVDEFS/norton_antivirus/static/navup8.exe
or
ftp://ftp.symantec.com/AVDEFS/norton_antivirus/static/

*.xdb: ftp://ftp.symantec.com/AVDEFS/norton_antivirus/xdb/

Run: Run navup8.exe to update virus definition and then remove navup8.exe. Finish.

I use Symantec AntiVirus Corporate Edition server Version 8, it's ok.
