Bitdefender or Avast, which antivirus software is a better choice in 2021?
Read this in-depth, data-driven Bitdefender versus Avast comparison to make a wise decision.
The number of devices connected to the online world is increasing with each passing day. The Internet has certainly brought great comfort to our lives, opening avenues that seemed to be impossible before.
We can now talk to distant friends and relatives, shop online without having to move an inch from the sofa, stream our favorite shows and movies, acquire education, and do many more things.
However, being constantly connected to the online world has made us more than a couch potato – it has made us more vulnerable to cyberattacks. Hackers can now invade our privacy by stealing photos or other valuable data, steal banking information, encrypt data and demand ransom, etc.
According to SonicWall’s latest cyberthreat report, nearly 10 billion malware attacks were recorded in 2019, which is more than the world’s population.
Similarly, the 2019 also saw 187.9 million ransomware attacks, 34.3 million IoT malware attacks and 4 trillion intrusion attempts.
The rise in the instances of such attacks comes at a cost. It is expected that the worldwide spending on cybersecurity will touch $133.7 billion a year in 2022.
So, the question is: how much are you spending to safeguard data and privacy of yourself and your loved ones?
You may argue that premium anti-malware protection is only meant for businesses, and that individuals can rely on free antivirus software offered by almost all known brands.
But think again. Freebies come with only basic features and lack advanced tools needed to provide you with multifaceted protection and complete peace of mind.
Cybercriminals keep coming up with new and more sophisticated ways to breach your privacy and steal your data.
Only premium and reliable security suites can save the day for you, as they come with advanced features like multi-layer ransomware protection, anti-phishing tool, file shredder, firewall, parental controls, password manager, VPN, microphone and webcam protection, identity theft protection, and much more.
Antivirus programs from brands like Bitdefender, McAfee, Avast and Kaspersky are loaded with features that make you online world free of threats.
Best Antivirus Suite for 2021
Overall Score: 9.9/10
60-day money-back guarantee
Right now, we think that Norton is the best antivirus software your money can buy. It regularly earns perfect or near-perfect scores from independent labs and has the least impact on system performance compared to rival products. Its products combine top-notch security with an array of excellent security features and, best of all, offer exceptional value for money.
Overall, Norton 360 Deluxe (currently at 70% off) is our pick for the best antivirus suite in 2021. It is competitively priced and comes with almost everything you could possibly ask for, such as a firewall, a fully integrated VPN, dark web monitoring, cloud backup storage (50GB), a password manager, and parental controls. You can cover up to 5 PCs, Macs, smartphones or tablets with this suite.
If you want full-on identity protection and don’t mind paying more, Norton 360 with LifeLock Select (currently at 35% off) gives those in the US a full range of identity protection features, more backup space (100GB), as well as all the above.

Winner: Bitdefender. Both companies provide great features. But Bitdefender offers a much more comprehensive feature set spread across different suites.
2. Malware Protection
A reliable antivirus suite complements its impressive feature set with strong malware protection. This is the most testing function for any antivirus software.
Let’s look at test results from two independent organizations – AV-test and AV-Comparatives – and see how Bitdefender and Avast perform when it comes to malware protection.
AV-Test is among the top-rated independent organizations, which tests three key metrics of all antivirus products, including Protection, Performance and Usability.
In the AV-Test’s April 2020 Protection Test, Bitdefender displayed an outstanding defending capability and received a perfect 6 out of 6 score. Avast, on the other hand, was a bit short of the perfect score, receiving 5.5 out of 6 points.
Now let’s look at the AV-Comparatives’ test results. The organization runs three types of tests: Real-World Protection Test, Malware Protection test, and Performance Test.
In AV-Comparatives Real-World Protection Test, conducted in May 2020, both Bitdefender and Avast gave outstanding performances and bagged the highest ADVANCED+ (3-star) award.
Meanwhile, in the March 2020 Malware Protection Test, AV-Comparatives again handed Bitdefender the maximum 3-star ADVANCED+ award, whereas Avast received the 2-star ADVANCED award.
Winner: Bitdefender. Both companies performed well in independent tests. However, Bitdefender left Avast behind in two key tests, becoming the winner in this category.
3. System Performance
An antivirus should protect your computer while having a minimal impact on your system speed. Let’s see how the two brands compete in this arena and impact your system speed.
We’ll first look at the Performance Test results from the AV-Test Institute, carried out in April 2020. In this test, Bitdefender was exceptional once again and received a perfect 6 out of 6 score, whereas Avast was a little behind and managed to get 5.5 out of 6 score.
Now let’s take a look at the AV-Comparatives Performance Test results, issued in April 2020. Here, Bitdefender again notched the maximum 3-star ADVANCED+ award, while Avast received the second-ranked 2-star ADVANCED award.
Winner: Tie. Both companies gave a fantastic performance on the two independent tests and received matching scores. So, it’s a tie.
All renowned antivirus products have an interface that is not only intuitive but also straightforward as well. An interface is the software’s first interaction with the user and helps create a lasting impression.
Let’s see which among Bitdefender and Avast offers a more user-friendly interface.
Bitdefender interface divides into two main portions: a panel on the left side and a screen on the right side. The left panel lists different operations and notifies the system status. The screen side of the interface uses big quick access blocks to start or modify any function.
Bitdefender makes its interface intuitive and easy to use and is ideal for both new and expert users. At the same time, it incorporates the functionality to switch to more complex personalization for more seasoned users.
Now let’s see what Avast brings to the table.
Avast uses dark grey as the main color of its theme and contrasts it with bright colors like green, purple and orange. Avast’s interface comprises a vertical rail on the left side from where you can access the dashboard to see your overall protection status and run a scan.
The side rail also has separate tabs for Protection, Privacy and Performance categories from you can access these features in detail. For instance, you can control File Shield, Behavior Shield, Web Shield and Mail Shield features under the Protection category.
Winner: Bitdefender. While Avast too has a user-friendly interface. Bitdefender optimizes its interface for use by both casual and veteran computer users, which makes it a better design.
When it comes to pricing, the more the value, the better. Every customer gauges a price point based on what it brings in return. That’s why companies should be careful about how they charge for their products in comparison with their competition.
Let’s look at how Bitdefender and Avast compare in their pricing for different products.
Let’s start with Bitdefender pricing.
Bitdefender Antivirus Plus costs $19.99 per year for 3 licenses. Bitdefender Internet Security, the second tier of protection costs you $39.98 per year also for up to 3 licenses. But both of these products are only compatible with Windows.
Next comes the third package, Bitdefender Total Security which comes at $44.99 per year for 5 licenses.

Winner: Bitdefender. Bitdefender has priced its products quite reasonably compared to Avast, also offering more licenses with every tier. There’s a massive difference between the top-tier prices of both companies. So, Bitdefender wins this category.
6. Customer Satisfaction
It is imperative today for any company to give full support to its customers in case of an issue. This presence or lack of support adds a lot to the brand’s market reputation. Let’s see which of our competing companies is better at keeping its customers happy.
Our first source of feedback rating is the Better Business Bureau (BBB). They are an independent organization that collects customer feedback and average it out into letter rating from A to F. BBB awarded Bitdefender with an average C rating while awarding Avast with a perfect A+. This shows that Avast takes excellent care of its customers.
Now let’s look at our second source. Consumeraffairs.org is another platform to check customer ranking. The website collects customer responses and issues a 5-star ranking based on the positive or negative nature of the feedback. Bitdefender scored a 3-star rating on this site. Avast also matched Bitdefender on this platform and scored a 3-star rating.
Winner: Avast. Both companies received a similar rating from the second source, but Avast went way ahead compared to Bitdefender in its rating from the BBB. Avast is the obvious winner here.
There’s no questioning that Avast is a top-notch security company. But Bitdefender surges ahead with its focus on functional features, excellent malware protection, minimal impact on system performance, and good pricing structure. All of these aspects are hugely important.
Our recommendations: If you want to get the highest level of security and performance, there's no better choice than Norton, which protects over 50 million users worldwide.
After reviewing dozens of antivirus products from some of the biggest names in the cybersecurity realm, we believe that Norton 360 Deluxe is the best antivirus suite available on the market. It provides flawless anti-malware protection without slowing you down. Plus, you get almost all the advanced features you could ever want.
If you're willing to pay more for advanced identity protection features, we recommend Norton 360 with LifeLock select (only available in the US). It's a bit pricey but worth the price.
