Norton 360 wins this comparision with its offers budget-friendly options and complete cybersecurity suite, which includes LifeLock identity theft protection and credit monitoring. Norton's anti-malware protection earned near-perfect scores from independent testing labs.

Microsoft Defender adds additional protection for Windows users, like identity theft protection and device security alerts, which you won’t get with the free Windows Security program. 

Now that we’ve covered the basics, we’ll help you choose whether you want to go full throttle with Norton 360 or add more protection to Windows Security with Microsoft Defender.

Windows Security is often used in the same sentence as Microsoft Defender, but they’re not the same. Windows Security comes built into Windows 10 or 11. Microsoft Defender is an app that can work with Windows Security to check malicious links, protect your identity, and give you more web protection. And to add to the confusion, Microsoft Defender was formerly known as Windows Defender.

Norton vs. Microsoft Defender: which is better?

Norton vs. Microsoft Defender review at a glance

Both Microsoft Defender and Norton 360 are antivirus products. You can think of Microsoft Defender as icing on the cake. It gives you more internet protection than you have with Windows Security, the security software built into Windows 10 and 11.

Norton, on the other hand, has a full toolkit of security features and doesn’t need another app to provide strong threat protection for your devices.

Another difference between Norton 360 and Microsoft Defender is that with Norton, you pick a plan and buy the one with the features and price you want. This ranges from basic protection with the AntiVirus Plus plan to parental controls, a privacy monitor, and identity theft protection with Norton 360 with LifeLock Select. 

Microsoft Defender requires a Microsoft 365 subscription, which comes in two varieties: a Personal plan and a Family plan. The biggest differences between these two plans are additional device coverage, more cloud storage, and the Family Safety app.

The best antivirus software for Windows doesn’t necessarily have to be a Microsoft product, and Norton is worth considering.

How we test and rate antivirus software

We use our proprietary grading rubric in all of our testing, which considers ease-of-use, third-party testing scores, internal testing scores, price, compatibility, and features offered, among other metrics. 

This means that our testing process is designed to ensure that the product isn't too confusing, protects as it claims, and offers you a lot for a reasonable price. We download and run each program on our own computers on home networks, just like you would. Our ratings reflect the real-world performance of the antivirus product. This ensures that we can recreate a similar experience for you and give our best advice on whether or not it's worthwhile.

To learn more about how we test, check out our full antivirus testing methodology here.

Norton 360 pros and cons

One of the best antivirus programs available, Norton's security suite offers real-time protection against ransomware, spyware, phishing, and other threats.

It comes with a ton of security measures as well. Norton has features like a password manager, virtual private network (VPN), and identity theft protection. Norton protects up to 10 devices.

Norton gives you 24/7 support and has community and chat support features. If none of those options work for you, you can connect with support via social media on Facebook or Twitter.

Pros
  • Protection against all malware, ransomware, and hacking
  • Cloud backup and password manager included with all plans
  • Includes parental controls
Cons
  • No free version

Microsoft Defender pros and cons

While there are some similarities between Microsoft Defender and Norton, you’ll also see some staunch differences. The starting price for Microsoft Defender is almost as much as the top-tier plan you get with Norton.

We want to emphasize that although you’re not paying anything for Microsoft Defender, you can't use it without a Microsoft 365 subscription, which starts at $69.99/yr. Comparatively, Norton 360 with LifeLock Select only costs $99.99/first yr.

With device coverage, Microsoft Defender allows up to five devices per person and up to a maximum of six people if you choose the Family plan. Microsoft Defender doesn’t come with 24/7 customer support. So if you get stuck with a problem, you can either access the help feature in the Microsoft Defender app, use the website chat, or use the Microsoft community to ask questions. 

Again, we want to note that Windows Security comes built into your Windows PC, but Microsoft Defender requires you to purchase a Microsoft 365 plan. The prices we’re comparing for this review include the Microsoft 365 subscription plans.

Pros
  • Performed well in 3rd-party testing
  • Parental controls
  • Compatible with other antivirus
Cons
  • Struggles with phishing sites
  • DNS filtering only available on Edge
  • Cloud backup costs extra

Microsoft Defender doesn’t cost anything to download, but to use it, you must first create a Microsoft account and pay for a subscription to Microsoft 365. The lowest price you’ll pay for the software is $69.99/yr or $6.99/mo, which seems somewhat steep when compared to Norton’s starting price of $29.99/first yr for the AntiVirus Plus plan.

If you want the best value for your money and don’t mind sharing a plan with others, then the Microsoft 365 Family plan is the best value. For $3.00 more per month, you get coverage for up to six people as opposed to one. You also get up to 6 TB of cloud storage rather than only 1 TB of storage.

Norton considers the Norton 360 Deluxe plan the best value, and we tend to agree. It’s a solid midway point with protection for five devices, parental controls, and a privacy monitor — all for $49.99/first yr. You also get 50 GB of cloud storage. That’s not as much storage as Microsoft 365 offers, but for most people, it’s more than is needed.

If the Deluxe plan’s cost doesn’t fit your budget, Norton’s AntiVirus Plus plan comes with real-time protection, a password manager, and a firewall. Along with all that, you get 2 GB of cloud backup. We think $29.99/first yr is a fair price for this level of security protection.

Winner: Norton. Although Microsoft offers a lot of value, the price is much more than Norton's, and Norton also packs a punch with the features included.

When you glance at the table above, you’ll immediately notice a difference in features. Although Windows Defender is good for additional protection, it doesn’t come with all the security options you get with Norton. Of course, the plan you choose with Norton affects how much cloud storage you have and if features like dark web monitoring and the Privacy Monitor are included.

When you get Norton, no matter which plan you select, you get features like a firewall, cloud storage, and a password manager. Many antivirus products offer those separately, so it adds value when you can get everything in an entire antivirus suite. From what we can see, there’s nothing Microsoft Defender offers that you can’t get with a Norton antivirus plan.


One thing we liked is that Microsoft Defender lets you know if there are recommended actions you should take for more security. You’ll have a view of what settings are active and which ones need to be turned on for better protection — these are cross-device security alerts, meaning alerts are sent to all devices on your plan.

The Microsoft Defender dashboard redirects you to Windows Security for any antivirus-related features. Both dashboards were intuitive and easy to use.

Winner: Norton is the winner. With all the features you get, it’s easy to see why it clears the deck when comparing it to Microsoft Defender.

Norton vs. Microsoft Defender: test results

When you purchase an antivirus program, you want to know it does the job right. Many products boast about what they can do, but how do you know if it’s true? That’s why we rely on third-party testing sites to deliver the goods. For this review, we used AV-TEST.

Windows results from Mar/Apr 2024. macOS test results from Dec 2023. Android test results from Mar 2024.

Microsoft Defender held up well during testing, protecting and detecting 100% of malware attacks in March and April of 2024. The other result we noticed was that it caused frequently used applications to install more slowly. On a standard PC and a high-end PC, it scored 22% and 26%, respectively, while the industry average was 15% and 16%. However, it still managed to receive a perfect performance score. We were also pleased to find that it didn't have any false positives during this round of testing. 

On the other hand, Norton seemed to slow down the installation of frequently used applications more than Microsoft Defender, with scores at 30% for standard PCs and 25% for high-end PCs. However, Norton had strong scores across the board for protection, performance, and usability. As a bonus, Norton also had perfect third-party test results for macOS and Android.

Winner: Norton. Norton had perfect third-party test results for macOS and Android. Until more recently, Norton also had perfect scores for Windows as well. Although Microsoft Defender did clock a perfect score for Windows testing this time around, you get more compatible operating systems with Norton.

Microsoft Defender, previously Windows Defender, is easy to use, and we had no learning curves with the program’s interface. However, this could be because the software doesn’t include many features. For example, you won’t have a VPN or password manager, to name a couple of advanced cybersecurity features you might miss.

One thing we noted while testing Microsoft Defender is that it directs you to the Windows Security settings for anything related to your antivirus protection. Thankfully, both apps mimic all the other dashboards in your Windows settings, and a majority of the security features are already toggled on.

Microsoft Defender includes Device security tools like Core isolation, Security processor, and Secure boot.

Norton’s user interface works seamlessly, and we had no lags in speed while testing the product. We even gave it a go with multiple browser tabs open. Everything worked without any issues. The full scan took only a few minutes to check over 600,000 files.

With Norton, we noticed that as soon as the scan gets finished, the number of files disappears. If you want to know how many files Norton checked, you need to look fast.

As we often find when reviewing antivirus software, some features don’t work with macOS. For instance, you won’t get the advantage of the Power Eraser tool or parental controls. 

We tried Norton's junk file cleaner, which took a few minutes to identify files we could safely remove to improve our device's performance.

But you still get plenty of options if you're a Mac user. The dashboard monitors different categories of personal data Norton checks for on the dark web. The VPN is easy to use and allows you to watch your favorite streaming service.

Although we didn’t need to contact Norton customer support, we were pleasantly surprised with all the options available for assistance. The only customer service feature not listed is email support. Otherwise, you have plenty of ways to get help when you need it. Going above and beyond, Norton also has a support team you can message on Facebook or Twitter. The live 24/7 customer support means you can get assistance anytime, day or night.

Microsoft Defender comes with some options if you need support. There’s a community where you can chat with other users, or you can also log in to your 365 account and fill out a support ticket. Microsoft also has articles in case you have common issues, like problems downloading the app.

Winner: Norton wins. It is probably no surprise that Norton is our pick here with all the ways to contact customer support. As far as compatibility, it’s not that Microsoft Defender isn’t easy to use, but Norton has many features that are also simple to navigate.

Norton vs. Microsoft Defender: which is better?

Norton is the pinnacle of protection and security features. Granted, some features may not work for Mac users, but that’s nothing new in the antivirus world today. Still, when pitting these two antiviruses head-to-head, we have to go with Norton. There are so many options to use, and you get solid security protection for a reasonable price.

Microsoft Defender antivirus is a good addition if you have Microsoft 365 and want more protection on your Windows machine than Windows Security can offer. But it isn’t exactly what one would call a security suite since it’s missing certain security features you can find with Norton.

If you’re a Windows user and want to add Microsoft 365, Defender is a good option to fill in any security gaps. Otherwise, we think Norton antivirus is the better software when you want a host of features like a smart firewall, secure VPN, a password manager, and more.
