Norton antivirus browser page loading issues

Since I installed Norton on multiple computers (as my license covers up to 10 devices), I’ve been experiencing issues with web pages on my browser. Pages are not loading correctly. For example, when I open YouTube, it appears as if the page hasn’t fully loaded, with many grey boxes instead of video previews. I have to refresh 2-3 times before it finally loads correctly.

The same issue occurs with Facebook. When I open the page and try to log in, it looks as if the page hasn’t loaded properly, with all the buttons and bars misplaced, making it impossible to click anything. I refresh the page, and then it works fine.

On one computer, I uninstalled the antivirus, and everything worked well for 2-3 days. However, when I reinstalled it, the same issues reappeared.

For reference, all the computers are on the same network, and we have 1Gb fiber internet, so I don’t believe it’s an internet connectivity issue.

Is there a known issue with Norton affecting browser page loading or web content display? Has anyone found solutions to this problem, such as adjusting Norton settings or disabling specific web protection features?
