Let’s dive into details.

1. Features

Windows Defender — which has now evolved into Microsoft Security — is the free, pre-installed security suite that comes with Windows.

Unlike other antivirus companies that offer a diverse range of antivirus suites, Microsoft only offers a free version of Window Defender. The freeware is limited in terms of features and extra utilities, but it does have essential features that should be there in an antivirus suite.

You can run different time of scans, namely Full Scan, Custom Scan (checks specific files/folders), and Offline Scan (useful if you’re infected by malware). Perhaps the most useful feature of Windows Defender is its Firewall; it monitors network connections and prevents hackers from gaining access to your network.

Another handy module included in Windows Defender is parental control. It lets you see which sites your children visit online (but only when they use Microsoft Edge), set when and how much time your kids can use their devices, and more.

SmartScreen Filter is also part of the freeware. It blocks malicious websites and also checks downloads for malware, but it only works on Microsoft’s own Edge browser, making it of little use to you if you prefer Chrome or Firefox. Protection against ransomware and rookits is included in the suite.

That’s pretty much all that is included in the Windows Defender. If you want additional features/utilities and added protection, there is no paid-for upgrade or additional add-ons offered by the Microsoft.

Now, let’s look at what McAfee has to offer.

Unlike Microsoft, McAfee doesn’t offer a free antivirus product.

Previously, McAfee used to offer a range of antivirus suites, including McAfee Antivirus Plus and McAfee Internet Security. Now, it only offers the McAfee Total Protection package, which comes in four versions: Single Device, Individuals/Couples, Family, and Ultimate.

McAfee Total Protection is a full-blown antivirus suite, boasting almost all the features you can ask for.

Along with excellent, award-winning protection against all sorts of malware, it includes home-network protection (protects your Wi-Fi network), an advanced Firewall, and a file shredder (helps delete your sensitive files securely so no one can recover them).

You will also get performance optimization tools that rid your computer off junk files and speed it up. The suite also offers a vulnerability scanner that checks for outdated software and other issues, and Silent Mode (prevents notifications for interruption-free experience).

The package also boasts encrypted storage that protects your important and confidential files on your PC with 256-bit AES encryption.

Besides, you get a password manager, a secure VPN, a safe browser, online support, and help from security experts.

The Single Device package lets you protect any one device, be it a computer or a smartphone. If you want to cover more devices, you can go for the Individual/Couples plan, which offers protection for five devices.

The Individual plan also comes with McAfee’s Identity Theft Protection Essentials package, which helps you thwart possible identity theft.

The we have the Family plan, which covers 10 devices and also includes McAfee’s Safe Family parental controls.

Lastly, the Ultimate plan offers all of the tools mentioned above as well as the Identity Theft Protection Plus package. This feature offers identity theft protection, credit monitoring, 24/7 dedicated agents and insurance of up to one million dollars in case of losses.

Note: McAfee’s products are compatible with both Windows and MacOS.

Winner: McAfee.

2. Malware Protection

Malware protection is the primary job of an antivirus program. If a product doesn’t perform well on this metric, it may not be worth at all.

To see how Windows Defender and McAfee fare in this category, we will take a look at the recent malware protection tests conducted by reputable antivirus testing labs like the AV-Test Institute and AV-Comparatives.

Let’s first consider AV-Test. The lab’s most recent evaluations were conducted in February 2021.

Several popular antivirus products were evaluated for 258 samples of zero-day malware threats and 9,972 samples of widespread malware.

McAfee earned a perfect 6 out of 6 star rating thanks to its excellent performance.

Windows Defender’s performance was equally impressive, as it also achieved the highest possible score.

The AV-Comparatives lab runs two kinds of tests to evaluate the anti-malware capability of an antivirus product. These tests are the Real-World Protection Test (exposes a product against real-world conditions) and the Malware Protection Test (which gauges a product’s ability to prevent malware infections).

The latest Real-World Protection Test was conducted in July-October 2020. Windows Defender (Microsoft) received the highest ADVANCED+ award. Of the 758 test cases, Defender blocked all the infected files, showing a protection rate of 100%.

McAfee secured a success rate of 98.5%, as it blocked 747 files. It received the second-best ADVANCED award for this performance.

In the AV-Comparatives’ most recent Malware Protection Test, conducted in September 2020, both antivirus products switched sides. McAfee received the highest-possible ADVANCED+ award, whereas Windows Defender could only manage to get the two-star ADVANCED award.

So, it’s evident from the three protection evaluations that both McAfee and Windows Defender fare equally well in terms of malware protection.

Winner: Tie.

3. System Performance

Apart from protecting your computer, an excellent antivirus program must also not slow down your computer while performing operations in the background.

AV-Test’s latest performance evaluation, conducted in January-February 2021, measured the impact of an antivirus suite on system performance.

The performance was tested against different indicators like downloading and opening apps, launching popular websites, copying of files, etc.

Just like in the protection test, both McAfee and Windows Defender clinched a perfect 6 out of 6 score in the AV-Test performance evaluation as well.

In its latest performance test, AV-Comparatives measured similar operations, such as launching applications, installing /uninstalling applications, downloading files and browsing websites.

The AV-Comparatives also assigned an impact score to each product based on its performance. The lower the score, the better.

McAfee received an excellent score of 1.1 and was among the top three products, only behind F-Secure and K7 antivirus.

Windows Defender was the worst performer, receiving a much higher impact score of 27.2. In fact, it was the only antivirus product that was given the lowest STANDARD award.

The results clearly show that McAfee puts less impact on your computer than Windows Defender.

Winner: McAfee.

4. Interface

First, let’s look at Windows Defender’s user interface.

Back in the day, Windows Defender’s interface used to be slightly outdated, but it is no longer the case. Lately, Microsoft has turned the software into a centralized portal from where you can easily manage your security and privacy at one place.

The interface is simple and elegant — in colors of white, light gray, and blue – and would sit nicely on any Windows operating system.

The Home window is your “security at a glance.” It contains quick links to the following modules: Virus & Threat Protection, Account Protection, Firewall & Network Protection, App & Browser Control, Device Security, Device Performance & Health, and Family Options.

Each module contains related features and their settings.

Now, let’s look at McAfee’s interface.

McAfee’s interface has also undergone quite a transformation, becoming much simpler and brighter.

The new interface is also more efficient

A horizontal menu at the top has following five modules: Home, PC Security, Identity, Privacy, and Account. The Home tab, which is the default screen, displays your protection status and also has buttons to run different types of scans. You can also clear your browser of cookies/trackers directly from this window, too.

The next three modules contain relevant features and their settings. The Account window has information about your plan.

Since Windows Defender is free and McAfee does not offer a freeware, no comparison can be drawn between both software in this category.

Winner: No comparison.

The Bottom Line

The main difference is that McAfee is paid antivirus software, while Windows Defender is completely free. McAfee guarantees a flawless 100% detection rate against malware, while Windows Defender’s malware detection rate is much lower. Also, McAfee is far more feature-rich compared to Windows Defender.
