Norton Antivirus solutions review

  • on May 23, 2021

First seen way back in 1991, Norton AntiVirus is one of the best-known brands in the security business. 

The current release, Norton AntiVirus Plus, is a powerful suite that comes absolutely stuffed with high-end features: antivirus and anti-ransomware, malicious URL filtering, an intelligent firewall, password manager, speedup tools, and simple cloud backup with 2GB storage.

Please note

This is our all-in-one roundup reviewing every NortonLifeLock consumer security solution for 2022. On this page, after our brief intro, you’ll find

(a) a full evaluation of the entry-level Norton AntiVirus Plus, along with our reviews of the additional features incorporated with the rest of the range: 

(b) Norton 360 Standard, and

(c) Norton 360 Deluxe, and

(d) Norton 360 with LifeLock

You can jump to the reviews of those individual products by clicking on the links in the bar at the top of this page, but bear in mind that this article is really designed to be read all the way through, as the features of Norton AntiVirus Plus are also present in the higher-level security suites.

The package covers Mac as well as Windows, and a single device, one-year license costs $15 initially, $60 on renewal. That’s fair value for the features you’re getting, but if you’re only looking for the basics, there’s money to be saved elsewhere. 

Bitdefender Antivirus Plus doesn’t quite match the Norton feature set, for instance, but it can protect three devices for only $25 in year one, $60 on renewal. Billing is more flexible, too, and you can save money by adding more devices and years to the subscription. Norton AntiVirus Plus is strictly one device, one year.

If AntiVirus Plus isn’t enough, the Norton 360 range adds more features and covers up to five devices, which can now be Android and iOS, as well as Windows and Mac.

Norton 360 Deluxe, one of the best Mac antivirus, includes unlimited access to Norton Secure VPN (also for up to five devices), protects against unauthorized access to your webcam, and ramps up your online backup space to a very useful 50GB, up from 10GB last year. Parental controls help keep your kids safe online, and dark web monitoring raises the alert if your email address is being sold online.

Despite all this extra power, the suite is still only $35 for one year license, $105 on renewal. That could be worth buying for the VPN alone, at least for the first year- even a value provider like Private Internet Access charges $40 for a one-year license.

Upgrading to Norton 360 with LifeLock Select bumps up your backup space to 100MB, and, for US users, adds a full identity theft protection service: Dark Web monitoring, credit monitoring, real-time alerts, US-based identity theft restoration specialists and a million-dollar insurance package. It’s an impressive package, though with a huge amount of small print to browse (check out the details here).

Norton 360 with LifeLock Select is priced from $99.48 in year one, $150 on renewal. It’s fair value, but you might be able to save a little elsewhere. McAfee Total Protection isn’t as powerful as Norton 360 Deluxe, but it includes identity theft protection, and is priced at a bargain $65 for year one, though this jumps to $160 on renewal.

Can’t make your mind up? There are 30-day free trials for just about everything available on Norton’s Downloads page, and if you sign up and have regrets, you’re also protected by a generous 60-day money-back guarantee.

Norton AntiVirus Plus


Norton AntiVirus Plus installation proved straightforward. The package grabbed 1GB of storage space, average for a suite with this level of functionality, and added only two major background processes to our system.

Running PCMark Professional before and after installation, though, we found our score dropped by 4.8%. That’s better than the 5.9% drop we saw with Sophos Home Premium, but most packages only see a 1-2% drop, and Avira and McAfee had barely any impact at all.

AV-Comparatives’ October 2021 Performance Test showed Norton performing a little better, but it was still a mid-range 9th out of 17 in terms of its impact on system speed.

Malware often tries to disable antivirus before launching a full attack, so the best antivirus make real efforts to protect themselves from attack. We test this by running various attacks of our own, including closing processes, deleting files, unloading drivers and disabling services. We were able to close the process powering Norton’s user dashboard, but the package’s core files, services and drivers were fully protected, and our security remained active at all times.


Norton AntiVirus Plus has an odd interface, split across two windows. 

Its My Norton screen looks good, but makes poor use of screen real estate, with the bulk of its dashboard taken up by a wallpaper image of someone trekking along a mountain trail, a handful of buttons to launch key tools, and most of the rest being just white space.

There’s more functionality and control available, but you must open a separate Security window to access it, and we found it took longer than expected to find our way around Norton’s many features.

Antivirus is relatively straightforward, though. Smart Scans are only a click away, whatever interface you’re using. These run a Quick Scan for malware, identify network security problems and check for what Norton calls ‘Advanced Issues’ (in practice this just gave us a list of tracking cookies to delete.)

A separate Full System is on hand, if you need it. And a highly flexible custom scan feature gives you all kinds of options. We set up an example to automatically scan our Downloads folder every three hours, for instance, but only when our system was idle and on AC power.

Scan times are reasonable, with 50GB of test data taking 29 minutes for the first scan, dropping to 4:13 next time, within the range we’d expect for this type of suite. Bitdefender’s first scan was slower (50 minutes), but it dropped to 50 seconds next time; Avira began a little faster at 26 minutes, but there’s no ‘scan only new and changed files’-type optimization, and it took the same 26 minutes each time.

An option to run Norton’s Power Eraser gets you a more aggressive detection and repair technique which might remove trickier threats. That’s welcome (it’s a capable tool), but you don’t need to buy the package to get it. Norton Power Eraser is available for free on the Norton website.

But if you’re unsure whether you’re infected and just want to find out more, a Norton Insight tool reports on the reputation of various files on your system. 

This works like a security-focused version of Task Manager. The main window lists running processes, with a Trust rating for each, an indication of how many others use them, their system impact and more.

This has some major benefits for expert users. Even if you’ve been infected by a threat so new that Norton can’t detect it yet, Insight may still be able to point to a possible issue, highlighting active running processes or loaded modules which you don’t recognize, and it’s never seen before. If you’ve enough Windows experience to go manually hunting for malware, this is a very handy tool to have on your side.


AV-Comparatives’ Real-World Protection Test is a comprehensive benchmark which pits 17 of the top antivirus engines against some of the very latest malware.

Norton’s results have varied a lot in 2021, from 99.5% protection and 10th place in the February-May tests, to 100% and a third place in the July-October report. (That’s third instead of equal first because it had the highest number of false positives across all contenders at 37: seven of the AVs tested had none at all.)

AV-Test’s Windows 10 Home User reports are far more consistent, with Norton earning a maximum six points for Protection, Usability and Performance in every test over the last year (December 2020 to October 2021.)

SE-Labs’ Q3 2021 Home Anti-Malware Protection report was less impressed, ranking Norton sixth out of nine with a Total Accuracy Rating of 96%.

We ran some simple tests of our own, using common malware-like tricks to download malicious files with standard Windows tools. Norton AntiVirus Plus performed well, blocking most of our simulated attacks at the behavioral level, before the files could be downloaded. And although it ignored our exploit attempts a couple of times, the file detection layer detected and quarantined the file just as soon as it hit our hard drive.

We weren’t finished yet, though. We’ve also created a custom ransomware-like program which spiders through a test folder tree, opening and encrypting common images, videos and document types. As it’s never been released, Norton can’t have seen it before, making this a good test of its ability to detect and block ransomware by behavior alone.

We ran our test threat, Norton AntiVirus Plus detected and killed it, and a few seconds later, warned us about the problem. While that’s good, we found our threat had encrypted 57 files before it was stopped. In previous tests we found both Bitdefender and Kaspersky recognized the danger after it had accessed a maximum of ten files. And even better, they recovered the originals, ensuring we didn’t lose any data at all.

Browsing protection

Norton AntiVirus Plus uses multiple layers of protection to help keep you safe online.

Norton Safe Search is an Ask-powered search environment which highlights trusted and dubious websites; if you’d prefer to stick with Google, the Norton Safe Web extension adds site ratings to your search results; and if you hate weighing down your browser with security extensions, just ignore them – the main Norton engine detects and blocks malicious domains at the network level, anyway, allowing it to protect all your applications.

This all worked well for us, blocking the malicious URLs we tried without difficulty. We tried accessing them from a tiny browser we’d written ourselves, to confirm URLs were blocked at the networking level, and that worked, too; our app was blocked whenever it tried to access the page, with Norton displaying a detailed alert explaining why.


Norton AntiVirus Plus, as the name suggests, isn’t just about squashing malware. It also has some very useful bonus features.

An intelligent firewall lets you know if untrusted programs are trying to make an internet connection, and asks if these should be allowed. While that’s a potential hassle for the user, we find it only happened in the most extreme circumstances, and we were given plenty of information to help us decide.

Instead of the usual ‘dubious.exe is trying to get online, allow? ‘ warnings, for instance, the firewall warned us that our test program wasn’t digitally signed, had been released less than a week ago and had very few users, as well as showing us the URL it was trying to reach. You’re able to allow or block the connection in a couple of clicks, and optionally have the firewall remember your decision, ensuring you won’t be asked again.

If you know what you’re doing, heading off to the Settings dialog gets you access to all the gory low-level technical details, right down to the detailed rules governing each protocol and traffic type.


The big surprise with Norton AntiVirus Plus is its bundled backup tool. Kaspersky offers backup, but only to local drives, and in its high-end Total Security suite. Norton’s backup is a hosted service which comes with 2GB of online backup space in AntiVirus Plus (it supports local destinations, too.)

The app is seriously short on features. If you’re hoping to get control of archiving, encryption, versioning, forget it – there’s none of that here.

We’ve no complaints about ease of use, though. By default, the app backs up your Office documents, pictures, music, contacts, internet favorites and so on. If that totals less than 2GB, you can back up your data to the web in a click; if it’s more, you’re able to exclude individual files, folders or entire files, or you can choose a local drive as the destination, instead.

Backups can be run on demand, or scheduled to automatically run every day, week or month, and a ‘Run only at idle time’ option should ensure it won’t get in the way when you’re busy.

There’s not a lot of power here, and when Google Drive gives you 15GB storage for free, Norton’s 2GB doesn’t exactly seem generous. It’s 2GB more than you’ll get with most antivirus packages, though. Upgrading gets you more, for example 50GB with Norton 360 Deluxe. The ability to set up a genuinely useful online backup in seconds is welcome, too, especially for users who aren’t so technical, and the service does add some value to the package.


Norton AntiVirus Plus includes a handful of simple maintenance tools designed to speed up your PC.

Optimize Disk is a disk defrag tool which rearranges how files are placed on your hard drive to maybe improve performance. At least, that’s the theory: the technology doesn’t make much of difference with modern SSD drives. And when we tried Optimize Disk on our test system, it appeared to be using the standard Windows defrag tool underneath, anyway. If you’re interested, you can try that now, for free (click a drive in Explorer, click Drive Tools > Optimize.)

File Cleanup is one of the most underpowered junk file finders we’ve seen. Run the tool, it deletes Windows, Chrome and Internet Explorer temporary files, and – that’s it. There’s no attempt to confirm whether you really want to wipe these files, they’re just deleted immediately, and it doesn’t even tell you up-front how much space it’s freed up. (The information is available, but you must click a couple of links to find it.)

There’s really no reason for this tool to exist, as it doesn’t fully clear your Chrome history, and even Windows’ standard Disk Cleanup tool does a significantly better job of finding system leftovers. We ran Norton’s File Cleanup, then tried Disk Cleanup, and it identified 1.43GB of extra files we could safely wipe. 

The pick of the performance tools, by far, is the Startup Manager. Not only does this display the programs set up to launch along with Windows, but it also tells you their level of resource usage, how commonly they’re found across Norton’s other customers, and gives you the chance to delay the app’s start or disable it entirely.

There’s a surprising amount of detail about each app’s performance, too. In a click or two you’re able to check on a summary of an app’s CPU and RAM use, disk reads and writes, and you can even view a scrolling graph showing the app’s CPU usage over the past ten minutes.

The average user probably won’t care much about any of that, but if you’re more experienced, and genuinely looking to identify the most resource-grabbing processes on your system, Norton’s performance monitoring is a helpful extra which you won’t get with any of the competition.

Final verdict

Powerful, and with more features than some high-end suites, there’s a lot to like about Norton AntiVirus Plus. The package didn’t perform quite as well as the top suites in our anti-ransomware test, but it blocked the threat, and overall, it’s a quality antivirus app and security suite. Well worth a try.

Norton 360 Standard

Norton 360 Standard, the baseline plan of the Norton 360 range, is essentially Norton AntiVirus Plus with webcam protection, an upgrade from 2GB to 10GB of backup space, and unlimited use of Norton Secure VPN for a single device.

This isn’t just for PC and Mac any more. Android and iOS apps enable protecting your phone or tablet, too.

Prices start low at $25 for a one device, one-year license, rising to $85 on renewal. That first-year price is a good deal, especially if you’ll use the VPN and don’t mind the single device restriction – most specialist VPN providers charge $40 or more for their one-year plans (although they’ll typically cover five devices).


Unusually for a bundled VPN, Norton Secure VPN is fully integrated with the suite interface. There’s no need to open extra app windows or scroll through lengthy lists of countries to find what you need: just click the Turn On button and you’re automatically connected to the fastest server outside of your country.

That scores well for anonymity, as websites will always think you’re in another country, but it could be inconvenient if geoblocking leaves you unable to access some local sites. 

If that’s an issue, you can switch back to the standard ‘choose a country’ list. There’s a decent selection of 31 countries to choose from, but it’s strictly country-only, with no region or city-level options. 

The location list doesn’t have a Favorites system. The countries appear in a tiny box which only has room to display three locations at once, too, forcing you to spend more time scrolling to find what you need. 

The VPN has gained a host of new settings since our last review. It can automatically connect when you access insecure networks; ad and tracker-blocking helps preserve your web privacy; split tunneling enables deciding which apps use the tunnel, and which don’t; and a kill switch tries to protect you if the connection drops.

Some of these features perform well. Auto-connect and split tunneling work as advertised, for instance. And the app now properly raised a notification if our connection dropped, ensuring we knew when our traffic was unprotected.

The kill switch wasn’t as successful. It kicked in whenever we forcibly dropped the VPN connection, ensuring our real IP address didn’t leak: good news. But the kill switch blocked our internet so well that the app couldn’t reconnect: we had to turn off it off before we could connect again. 

Our performance tests showed Norton achieving 280-290Mbps on a 1Gbps connection from a UK data center. That’s good for an IKEv2 connection, but NordVPN and many WireGuard-equipped VPNs reached 750Mbps and more.

It was a similar mixed story on unblocking, where the VPN got us into BBC iPlayer and Amazon Prime, but not US Netflix or Disney+.

Put it all together and Norton Secure VPN is far from the worst service we’ve seen. But it’s not a great one, either. The VPN adds some value to Norton 360, but it doesn’t begin to compete with the best of the specialist VPN providers.

Webcam protection

Norton 360 includes its SafeCam webcam protection, which alerts you to untrusted apps trying to access your camera, and gives you the chance to allow or block them

That’s not as much hassle as it sounds. By default, SafeCam automatically allows known good apps to access the camera, so you’ll rarely see any alerts. And if SafeCam does ask permission for something, choose the ‘always allow’ or ‘always block’ options, it’ll remember your decision, and you won’t be prompted again

We found this worked exactly as it should: our most trustworthy tool was automatically allowed its capture, while our little-known app raised an alert. That works as a default setting for us, but if you prefer, you can turn off the ‘automatically allow good apps’ option to be prompted for everything, or you can turn off SafeCam entirely.

Mobile apps

Norton 360 Mobile Security for Android is a capable app which includes all the key tools from the desktop edition, and adds a pile of more mobile-friendly extras.

Automatic and on-demand scanning catches malware before it can launch, for instance, while web protection keeps you away from dangerous links. Testing shows Norton’s engine is very accurate, with AV-Test’s Android reports rating it a maximum 6/6 for protection in all six tests over the past year (November 2020-September 2021.)

The app includes Norton’s Secure VPN, allowing you to protect your wireless traffic with a tap.

Elsewhere, Norton 360 helps you avoid issues by displaying key details on apps from within Google Play, before you install them. You’ll see if the app has privacy risks, includes intrusive ads, makes excessive use of your battery and data, and more.

Recent additions include SMS filtering which checks texts for dubious phishing links, and the ability to detect and warn you if you’re connected to a potentially unsure network.

Norton Mobile Security for iOS is simpler. You still get Norton’s excellent web protection, along with the new SMS filtering, and a Wi-Fi security layer to alert you to dangerous networks: more than enough to be useful.

The mobile apps don’t quite have all the features you’ll see with competing apps (there’s no anti-theft, for instance), but there’s still a lot to like here. And if you’re unsure, check them out – they have trial versions available.

More features

Norton 360’s spam filter doesn’t get much attention on the website, maybe because it’s relatively basic. It mostly only integrates with Outlook, for instance (although it will work with Windows Mail on Windows 7), and it’s strictly POP3 and SMTP only – there’s no support for POP3 with SSL, IMAP or Exchange accounts.

The filter has no way to tweak its strength, either. If you don’t get the results you need, your only option is to add email addresses to Allowed and Blocked lists.

We’ve seen better spam filters, but you don’t have to use it. If it doesn’t work for you, turn it off and find an alternative.

Users in some countries – Australia, Canada, Germany, Japan, New Zealand, UK, US – also get Norton’s Dark Web Monitoring, one of the features of its LifeLock Identity Theft Protection service. Set it up and LifeLock monitors Dark Web sites where stolen data is regularly traded, and if your email address turns up, you’ll get a warning.

Many vendors offer similar-sounding features, but if you’re comparing packages, be sure to check the details.

Smaller AVs sometimes advertise ‘data breach monitoring’, for instance, but expect you to run searches yourself. In many cases they use the Have I Been Pwned database, too, which you can check yourself, for free, whenever you like.

Norton’s Dark Web Monitoring is powered by a commercial identity theft protection service, and there’s no manual searching required. You just get on with your life, the package keeps watch in the background, and raises an alert if your details turn up in a breach. Much more convenient.

Final verdict

Norton 360 Standard is all about its Secure VPN. If you’ll use it, and don’t mind the single device restriction, it looks like a very good buy. If the VPN doesn’t work for you, there’s not enough else here to justify choosing the suite. Either look at upgrading to a higher Norton 360 plan, adding support for more devices and the full identity theft protection plan, or expand your horizons and check out some other vendors.

Norton 360 Deluxe

Upgrading from Norton 360 Standard to Deluxe is mostly about the numbers. 

Forget the measly single device license, for instance – Deluxe covers up to five PCs, Macs, phones or tablets. You’re able to install and use the VPN on all those devices, too. And your online backup space leaps from 10GB to a generous 50GB.

That’s more than enough to justify the price of $35 in year one, $105 on renewal. (Norton 360 Standard is only $10 cheaper initially at $25 for the first year, $85 afterwards.

There’s more, though, in the shape of Norton’s Parental Control system. It goes way beyond the usual security suite basics with detailed content filtering, GPS tracking for mobile devices, and in-depth monitoring which allows you to see everything from the search terms your kids use, to the websites they visit and the videos they watch. It’s a worthwhile addition to the suite, but beware, this doesn’t work with Macs.

It all makes for a quality suite which compares well with the competition. Bitdefender Total Security is a great suite which outperforms Norton in some areas (it stopped our ransomware simulator and recovered all damaged files, for instance), but it doesn’t have the Norton 360 VPN, online backup or dark web monitoring, and yet it’s priced at a very similar $35 for a five device, one-year license, and $90 on renewal.

If there’s the slightest chance that you might benefit from covering more than a single device, then, Norton 360 Deluxe looks like the best general-purpose option in the range. One for your shortlist.

Norton 360 with LifeLock

Upgrading from Norton 360 Deluxe to Norton 360 with LifeLock Select gets US users full-featured identity theft protection and other welcome benefits.

The baseline Norton 360 with LifeLock Select plan covers the identity theft basics – credit monitoring, SSN and credit alerts, stolen wallet protection, up to a million dollars to compensate you for lost funds and expenses, and US-based identity theft restoration specialists to help you recover from any problems. It’s priced at $99 in year one, $150 on renewal

The top-of-the-range Norton 360 with LifeLock Ultimate Plus supports unlimited devices, includes 500GB backup space, increases the compensation you can get for identity theft expenses and losses, and adds features like credit reports from three bureaus, and 401(k) and investment activity alerts. It’s $262 for the first year, $350 after that

There’s a lot of value here, even if you’re not entirely sure about the identity theft protection. Use Norton 360 with LifeLock Ultimate Plus to cover 20 devices for a year, for instance, and you’re paying just $12.60 each.

LifeLock is the headline feature, of course, but we don’t have the space to fully cover that here. If you’re interested, go take a look at the Norton site to find out exactly what you get with each package, then compare it with the competition, and see who comes out on top.
