I've a site with 30 computers on which I've updated the symantec corp server to but the deployment installation doesnt work and I've to manually uninstall first the actual version to install the new one. Is it a way to lunch an uninstallation script to clear my old version without doing a manual uninstallation on each computer???

many thanks for your help.

Kindly Regards.

would it be helpful to fix the deployment issue?
if your computers are all on the same network, then deployment should work.
i've found the following issues to be the main reason why deployment fails:
windows firewall is enabled (must be disabled)
simple file sharing is enabled (must be disabled)
the local Admin account on the computer does not have a password (you must have at least 1 local admin account with a password).

it helps to have service pack 2 because then it's easy to disable windows firewall.

as far as uninstalling symantec corp AV without fixing your deployment issues, there is an application symantec puts out called NoNAV that will uninstall it.  your issue is going to be that NoNav requires user interaction.

also, you should be aware that is suseptible to the vulnerability that was identified a few months ago.  you will need to run the patch which fixes the vulnerability after your installs are done.  if you fix your deployment issue, you can do the patch via client install.

this page shows which versions need to be patched, and provides the patches + instructions:
(note:  your current version also has the vulnerability)

oh... one more note ... is there a reason why you're upgrading to 10.0 when 10.1 is the latest version?

pull the uninstall string from the registry and launch it from the run line

if you open the registry...
click start -->run type regedit then hit enter
in the registry browse to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\
find the key for Symantec Antivirus then look for the value uninstall
copy the data section into the run line and hit enter

the data section will look something like this but not exactly as my machine as sav9 so the uninstall string is different
MsiExec.exe /I{848AC794-8B81-440A-81AE-6474337DB527}

as a side note you may need to change the /I to a /U

In fact, the AV server crashed due to a RAID error. The SAV has been reinstalled and now the clients can't be found when I do a search and so they aren't added to the AV group.

That's why I need an uninstall command easy to deploy on a netlogon script or via GPO followed by the silent SAV install.

I've already tried the nonav on the version 10 but it doesn't work very fine.

Your version SymShady seems to be really nice.

I will try it if there is no other option.

Many thanks for help

I've finally tested the command and this one is the correct one...

there is only one last problem, the uninstallation ask me for the password and I can't deactivate it through the Symantec Console... Do you have any idea how can I add it to the uninstallation command???

there is :  

msiexec /passive /x{46B63F23-2B4A-4525-A827-688026BE5E40}  ( to see the password dialog box )
msiexec /quiet /x{46B63F23-2B4A-4525-A827-688026BE5E40}

many thanks in advance for your support.

To disable the uninstall PW:


To disable the password for uninstalling Symantec AV though Symantec System Center

1.  In Symantec System Center, right-click the Parent Server or Client Group that manages the client you want to uninstall.

2.  Click All Tasks > Symantec AntiVirus > Client Administrator Only Options.

3.  On the Security tab, uncheck "Ask for a password to allow uninstall of Symantec AntiVirus client."
