From the original CD:

g:\SAV\setup.exe /a >> run in administrative mode

copy all files from unpack directory to your $OEM$\$1\install\SAV\

In your CMD file, put this :

ECHO.
ECHO Installation de Symantec Antivirus Corporate 9.1
ECHO Please wait...
start /wait %systemdrive%\install\NAV\Symantec_AntiVirus.msi /passive /norestart
start /wait %systemdrive%\install\NAV\SAVCE_9.0.0.1400_AllWin_FR.msp /passive /norestart
taskkill /IM LUCOMS~1.EXEe /F
taskkill /IM VPDN_LU.exe /F
taskkill /IM LUALL.EXE /F
ECHO.
ECHO Updating Virus Def ... Please wait ...
start /wait "%PROGRAMFILES\Symantec AntiVirus\VPDN_LU.exe" /s

Taskkill => kill LiveUpdate started from installer
VPDN_LU.EXE /s run liveupdate silently

This work fine from my french version XP SP2 / Corporate 9.1 FR

wouldn't this be easier?

"%install_dir%\sav\antivirus.msi /qb-! RUNLIVEUPDATE=0 REBOOT=REALLYSUPPRESS ENABLEAUTOPROTECT=1

just put the data1.cab in the same folder as the MSI and you're golden
