Tracking thread for Norton 25.9.xxx releases

Ok folks!! So here we go again. Its time once again to put this specific release version into a thread of its own and allow the thread to be tracked as with previous versions. Weird things have begun happening, and not to everyone at once but are happening nevertheless. Please allow me to start the thread with the following:

Windows 10 Pro: 22H2 build 19045.6396 (64 bit)

Norton 360 Deluxe: 25.9.10453 (build 25.9.10453.0)

The day began with the already noted and reported issue where opening the UI presents users with a white screen and spinning circle. I do not have a screenshot, trust me it happened. After about two minutes the UI opened and has remained usable since.
As the day progressed. Norton firewall is being a PITA with most everything I do today. Although after some short period of time sites DO open they are not doing as expected. A full reset of the firewall does NOT correct anything.

Being told there is an updated version released this is what I just got when manually running live updates:

[1] Rebooting the machine doesn’t clear anything and LU still fail.

[2] I will be linking other threads to this one as before to ensure we have them all in one place vice scattered about the forums.

The issues in the opening post for me, my side appear to be resolved with a AUTOMATIC LU fix put in place while away from this PC a bit under two hours ago. I now have the following that resolved the issues:

Norton 360 Deluxe 25.9.10453 (build 25.9.10453.953)
Virus definitions 250930-10
UI version 1.0.104

Hi, I hope I can add to this thread. I have just uninstalled and re-installed Norton 360 and thus is what I now have

Windows 11, version 25H2 installed 01/Oct/2025.
Live Update ran with no issues.
Is there anything else I should do ?

SA, Thanks for your help and patience.

@Jonathan_Allenby Yes indeed thanks for the post.. it looks like your virus definitions set was updated. Caveat is your version of Windows 11 is 25H2 as well. That is a plus-plus. Thanks again.

Hi SA, if we find any issues with this update, should we add them to this thread ?
I don’t want to keep coming up with issues but I am having an issue with the Cloud Backup, should I add this here ?
I also cannot close the control panel UI with the x in the top right corner - I have to use Windows Control Panel to stop the process.
Thanks, Jonathan

Yes indeed. If the issue is already listed just tag the thread with the same issue.
