How to uninstall Norton Security (Preinstalled Acer) quite / silent?


I need to uninstall Norton Security which is preinstalled on an Acer device.


The installtion File is not in the registry: HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall

The installation File is in : HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

Uninstallation String is : C:\Program Files (x86)\NortonInstaller\....\instStub.exe" /X /ARP

Sooo... this installation doesn't support quite or silent installation...

The Norton uninstaller starts and then i need to accept (Advertising) some stuff and then it will uninstall.

What or how can i uninstall this damn software without user interaction...?

I've tried to unistall it with Powershell, CMD(msiexec) and 3rd part Software... no luck.

Thanks in advance for your help.

  • VBScab, it's not that easy, as all the Symantec/Norton files/registry entries/services are prevented from being disabled/deleted as part of the AV/malware protection. Now if there was a way to script deleting the files/registry keys during a shutdown/startup, after/before the protections are running, that might be an angle. Anyone know how to do that? - johnskinnernavi 1 year ago

I've said this so many times...Apps are just a bunch of files and registry data.

If the uninstaller doesn't cut the mustard, just build an uninstalling MSI or script. By that I mean, not one that calls the vendor's uninstalling EXE, but one that deletes the files and folders, along with the registry junk. Remember to account for DLL unregistration and - not so common today - shared DLL count, if that's taking place.

You should try once in safe mode. otherwise re-install window OS. I think this is the only way to Remove the unwanted EXE.
