Same issue here. Main window pops up for no apparent reason. Doing it on two separate installations.
The icon on my Windows taskbar also flashes.

I’m having the same issue, just randomly pops up. Even when I’m in the middle of photo editing which causes lose of data on the edit.

This issue is happening to a number of people and is being discussed in this thread …
Norton 360 automatically opens start site after Windows 11 system startup since version 26.6.
This is meanwhile a well known issue.

I’m having the same issue since the last update a couple of days ago. Running Windows 10 Pro. Do they have a fix or work around? Incredibly annoying.
Still getting the Pop-Up Home Screen – still no idea if they even CARE how badly this impacts, annoys us

I just posted on this, then saw yours, i get that in middle of doing anything, so annoying and nuisance! Every evening now. If keeps on will just use windows one.
JUST popped up again for the morning – 9:51am PDT
browsing in Full-Screen, didn’t affect anything today
still ANNOYING to have my screen taken over, and having to close an unwelcome Pop-Up

fwiw ~ my understanding:
Norton released a backend fix for the Automatic UI Opening issue. Please run LiveUpdate and Restart the system to get the fix applied.
