Software to Compare
Norton 360
Bitdefender Total Security
Compare
Most Features
Core protection (AV engine, Heuristic engine)
Internet protection (Web filtering, Anti-Phishing, Antispam, Browser extension)
Proactive protection (Behavior blocker, HIPS, Sandbox)
Network protection (Firewall, Botnet protection)
Ransomware protection
Machine Learning and A.I. capabilities
Privacy protections (VPN, Anti-Tracking)
ESET with the settings well adjusted is great :) I do not change ESET for anything, it makes the machine fast, it has the best web protection for me, great protection against PUP / PUA, it is light and does not install several useless programs (VPN among others)

Note: It's just my opinion, I respect anyone who prefers another antivirus

Note 2: Sorry if I didn't choose any of the two options you put in the question

Even if i am a Bitdefender fan, i also like Norton 360, been using it for the last 5 months, never had a problem regarding the software itself, a few viruses blocked/ quarantined, never been infected, i like the settings of Norton, a while ago i had a file downloaded from a shady website, the other major AV's did detect the file as malicious, Norton didn't, i manually added the file to quarantine, and from quarantine options i sent the file back to Norton for analysis, less than 24 hr later, Norton was detecting the file as malicious. Manually can't add files to quarantine with Bitdefender or Kaspersky, unfortunately. You can't go wrong with any of them, both a light on the system, both are efficient/strong. Norton has more tweaking options, but not to make you confused, its all crystal clear. As far as the price, if you search on google i'm sure you will find license for any of them for around 20$-25$ 1 year 1/3 PC's.

Bitdefender is still a resource hog. Norton 360 considerably lighter : good webfilter , good behaviour blocked and signatures. Been using 360 for 3 months now and I am satisfied with it ( allthough eset smart security runs lighter ). You can get a good deal for norton 360 2 years 3 devices over at computeractivestore.co.uk if you want. Nortons firewall is on of the best in the market as well!

Norton may be lighter. However, the only way to tell how either will perform on your own system, is to try both. Just restore from an image, or use the vendor's uninstall tool, after uninstalling, to ensure that all traces are removed.

Well, both security solutions are pretty decent. I would go with Bitdefender. I had used it before for a period of time. I did have any system impact at all. From what I saw on the new 2021 version it is lighter and hopefully they fix bugs if any.
Stay safe.

I only had to sign in to my account when I first installed it.
It might have been my fault as I uninstalled,then when reinstalling the sign ins began and often did not connect, when I tried to contact support they kept pushing me to pay, Lifelock would never reset no matter what I did,also the web protection did not allow me to go to a site I go to often.,No thanks I pass on Norton

In general my experience with Norton these days has been very positive. It's usually very light and I haven't experienced any issues that I can think of. I can't say too much about its web protection, as I currently just have Norton install a test computer, that I do very little browsing on.

When I tried both I slightly preferred Norton -- both were similarly light but Norton "got out of my way" better than BitDefender did, though BitDefender was only mildly annoying in that it would remind me of browser plugins and other trinkets over the course of the next few days.
I don't know much about BitDefender's cloud, but Norton Insight actually uploads a fair deal of data back to Norton for anonymized statistics -- that's how they have insight not just to whether or not something is suspicious, but also its resource usage, crash proneness, etc. Norton's transparent about it -- if you go into the log view you can see everything it is uploading.

Overall this is a really close call. At the end of the day, honestly, the relative ease at finding inexpensive Norton subscriptions tips me a bit towards Norton.

Currently there isn’t an uninstall tool for the new Bitdefender version (would be 2021). Been waiting for one to try it out again. Personally I’d go with BD, but it’s definitely just up to personal preference.
