Windows Defender or Norton (Symantec), which antivirus software is a better pick in 2021?
Our experts have put together this comprehensive Windows Defender versus Norton comparison to help you make a wise decision.
In fact, almost two-thirds of IT security professionals are of the opinion that a cyber-attack carried out this year will most often be successful.
According to a Clark School study, their computers were attacked 2,244 times a day, on average, during research involving the behavior of “brute force” hackers.
So, what to do in such a dire situation? Well, the first order of things is to get yourself a premium antivirus software: one that will protect you against the latest malware threats and ensure the safety of your loved ones and yourself.

2. Anti-Malware Protection
Malware protection is the first and foremost criteria for any antivirus software to live up to. That’s why next we’re going to learn about the protection capability of both
We’ll look at three different independent test results from AV-Test and AV-Comparatives to conclude about the winner of this category.
AV-Test.org runs three different tests, of which the Protection Test is the first one. The institute analyzes and ranks different products on a scale from 1 to 6 (1 being the lowest score).
Windows Defender performed pretty well on the Protection Test and scored full 6/6 points.
Norton wasn’t behind and notched the perfect 6/6 score.
Next, we’ll go to AV-Comparatives for their Real-World Protection Test results. In this test, both products received the second-place ADVANCED award. The reason for landing at second place for both products was due to a high frequency of false alarms.
Winner: Both. Overall, both Windows Defender and Norton are neck and neck in terms of malware protection.
3. Impact on System Speed
The impact on system performance is part and parcel of an antivirus program. However, modern industry standards demand that the software should have minimal effect on a standard computer system.
So, let’s find out how our brands influence the system performance of the computers they protect.
In the Performance Test conducted by the AV-TEST Institute, Windows Defender got a 5.5/6 score.
However, Norton outperformed Windows Defender here and received the perfect 6/6 score.
Let’s also examine the Performance Test results from AV-Comparatives. Here, Windows Defender performed rather poorly being the only product to receive the STANDARD award out of all the products tested, which indicates dragging impact on system speed.
However, Norton was once again at the top here with the highest-ranking ADVANCED+ award.
Winner: Norton. Norton gave a top-quality performance on both independent evaluations while Windows Defender fell behind on both.
4. User Interface
An excellent user interface is vital for a software because it makes it easier for users to understand the features and functions integrated into a product. Such an interface has a design that showcases the services offered without vagueness or complexity.
So, let’s find out what kind of interfaces are presented by both Windows Defender and Norton.
We’ll start with Windows Defender.
Windows Defender offers a simple interface with all the functions being accessible from the Home screen. You can access them either from prominent icons on the screen or from a side panel on the left side of the interface.
You can easily switch between functions and utilities using the side panel, which means you don’t have to go back to the Home screen every time you want to access a different feature.
Overall the interface is functional, if somewhat straightforward for expert users. The interface does present a couple of challenges as it doesn’t offer room for customization nor scheduled scans.
Now let’s have a look at Norton’s user interface.
Norton also presents a simple interface; however, it is incredibly streamlined. All primary functions are accessible through prominent icons on the Home screen. The security status of individual features is also displayed under the icons.
You can also reach different settings, help, or search options through a sleek bar towards the top of the screen. If you wish to start a quick scan, you can do that through a button on the Home screen. All the security updates are also visible next to this button.
Norton has a fairly intuitive interface that is equally appealing for all kinds of users. However, customization is not an option that is generally required by more seasoned users.
Winner: Norton. Norton has a well-organized and intuitive interface, while Windows Defender has a basic-looking interface by comparison.

Winner: Norton. Windows Defender comes free of cost, but the value provided by Norton products is incomparable, if for a small price.
Next, we’re going to examine and compare the market share held by each company. For this purpose, we are going to look at antivirus market survey reports from OPSWAT and Statista to see how our products compare on this metric.
In line with the recent Anti-Malware Market Share Report from OPSWAT, Norton commands a significant 11.98% of the total antivirus market share. Similarly, the Statista survey report of August 2019 shows Norton at 10.27% market share.

Winner: Norton. As the survey reports demonstrate, Norton is hugely popular on the antivirus landscape compared to Windows Defender.
7. Customer Ratings
In the end, we are going to look at the customer satisfaction ratings of both products. We’ll go to two feedback collecting organizations, Consumeraffairs.com and G2, and see how customers rate the two products.
The Consumeraffairs.org assembles customer responses and classifies different products on a 5-star scale based on the average feedback for each software. This website awarded Norton with a 1 star only, which indicates a general dissatisfaction from customers.
Conversely, though, G2 gave Norton 4+ stars (4.3 score), which shows customers are generally happy with Norton services.
Windows Defender remained unranked by both sources either for lack of customer responses or for lack of complaints.
Winner: Norton. Although Norton got a poor rating from the first source, it received an excellent score from the other website. So, on average, we can say that Norton has a moderate collective rating. Whereas, Windows Defender has no scores to compare.
Norton has knocked Windows Defender in all categories bar one, i.e., Malware Protection. But despite that, Norton has proven to be an all-rounder and a comprehensive solution provider that excels in all areas and provides a complete security solution for your own and your family’s peace of mind.
