Norton randomly making my window lose focus?

I wasted several hours too and tried all kind of stuff before I found out it was Norton causing the problem. It’s just not worth it when there are so many other options out there. Just annoying because I already paid for the next half year.

Have any of you received the latest version release from Norton? If so please advise if anything has changed regarding the issues being reported.

That is the version I’m using. Same problem.

Are you all logged into Norton via the UI or logged out via the UI? Wondering whether that would make any difference. I am personally logged IN and not seeing nor can I duplicate the issues you are all seeing.

Oh, so it’s not only me. Norton UI CONSTANTLY steals the focus and it’s really really annoying. I am also using the latest version (25.10.10528 (build 25.10.10528.957)

Logged in. The issue comes and goes. Regardless of what exactly triggers it: it should not be difficult for Norton’s developers to review their code and make sure that a background process dose not take focus.

It is not always that easy as it is not affecting all Norton users. I have not seen this issue, and if it were widespread, we would see many more posts than we have.

It may come down to an incompatibility with some other software or hardware that is common to the users in this thread. The only way for Norton to diagnose something like this is for users to send logs for diagnosis. Send Norton product debug logs with Norton Support Tool

Same problem here, Nortonui.exe is stealing focus every few seconds. Typing a message is a chore like this:

I have updated Windows 11 to 25H2 and Norton to 25.10.10528 (Build 25.10.10528.0).

If the Norton 360-Window is open, the problem disappears, at least for a while, although the focus stealing is sometimes still happening according to the focus-monitor.exe, especially directly after switching apps.

The (a) problem here is that it is not immediately clear that Norton is the culprit. If it even is - maybe some other Windows-process is handing over focus erroneously.

Well, some people probably don’t realize that it’s Norton causing the issue and took other measures that made it go away, at least temporarily (like updating some other software). Yes, you’re probably right, it is probably triggered by some other software. It’s still Norton’s issue to solve though. They already got logs from users and replicating the issue has failed.

So if something happens at random, and you can’t replicate the issue, then my next step would be to review my code, rather than inconveniencing users further or endlessly looking through logs to find a commonality. I’d check at what points the process takes over focus and at what point it returns focus. Then I’d look at the code in-between. It could be that the process is getting ready to pop up a message for the user but then branches off into a check that kills that message and returns focus to windows. In that case you move said check(s) up in the code to the spot before the focus is taken away. I’d also look into what part is not executed if the user has the UI open.

I know these seemingly random bugs are the most difficult to solve and if this would be an expensive system, then I would work with Norton on it. But for a consumer software that I can easily change, I’m not willing to spend a lot of time with support if others have already done that without result.

I totally agree this should be fixed - we still have a years’ worth of subscription, running on 4 devices (only one of which has the problem, but on that system both Windows-users (local, non-Microsoft-account-connected) are affected) but this makes me look around for alternatives after being pretty happy with Norton since using it on Windows 98.
