While watching youtube videos on my Win10 x64 machine I lose internet connection, often and only with NSwB installed. At first I thought this may of been a Win10 problem but after reinstalling Norton 22.5.4 on this machine after using Windows Firewall + Windows Defender for the last few weeks and NOT HAVING this issue it has started up again.
I have to conclude that Norton is responsible so I will be restoring an image backup of my machine before Norton was installed.
Edit: To reproduce open a few youtube videos in new tabs, I used both Firefox and Chrome (here's some to start with - https://community.norton.com/en/forums/what-are-you-listening-right-now), watch them one at a time at their highest resolution and watch for the Windows Internet connection Systray icon to show a yellow exclamation point. This should not take long.
Thank you.
