I remember many website members being somewhat scathing about Norton in recent years.
I won't repeat what you've clearly already read - but I would wholeheartedly agree with them.
My personal opinion is that running a still-supported version of Windows, kept up-to-date with all security updates; along with a combination of fully up-to-date Windows Defender (which, to be clear, is now an excellent piece of software and not the dismal cluster**** it was several years ago) and Common Sense v1.0 is more than sufficient for the vast majority of use cases.
As an optional extra, Malwarebytes Anti-Malware will not go amiss - especially if you get it for free (e.g. by being a NatWest/RBS/Ulster Bank customer). It is designed to, and does, co-operate well with Windows Defender.
