Latest update, various things going wrong

I am Windows 10, older versions of Outlook etc, Chrome to internet, have Norton Safe Search, Norton Home Page, Ultimate Utilities, Anti-track, no parentals.  Latest Norton update seems to disallow ... opening links from emails, opening links even within internet sites (eg clicking on "sale" items within Healthspan, Boots or wherever).  So I cannot easily find and purchase items from online stores.  I tried using Edge but nothing changes.  I also had the Bonjour message but found the fix too complicated, so have just deleted the Bonjour message

I have to believe this is Norton as I don't do automatic updates on other programs.  I am very nervous to delete Norton and reinstall - what happens to my Password Manager etc.  Something went wrong with that Norton update ... what's happening and how will you fix it please?

Thanks
