Bitdefender vs Avira: Which Software Provides Better Malware Protection?

Malware protection component (also called detection engine) lies at the heart of a security product.

To find out which software is better in terms of malware protection, I will look at the most recent independent tests conducted by AV-Test and AV-Comparatives – two well-known and most respected antivirus software testing laboratories.

AV-Test most recent evaluations were conducted in July and August 2018. All participating products – including Bitdefender and Avira – were put to test against 275 samples of zero-day malware (also called unknown malware) and 19,747 samples of widespread malware (or known malware).

Bitdefender registered perfect results; it blocked 100% of both types of malware samples in both months, earning a full 6/6 rating from the experts in the ‘Protection’ category.

Apart from the slightly lower 99.2% protection rate against zero-day malware in June, Avira’s results were flawless too. It also received full marks from the experts.

To thoroughly examine how well a security product defends against malware infections, the experts at AV-Comparatives do two major tests: Real-World Protection Test and Malware Protection Test.

The recent Real-World Protection Test report published by AV-Comparatives includes combined results of all the tests conducted during February-June 2018.

Both Bitdefender and Avira received the highest ADVANCED+ award, due to their near-perfect protection rates of 99.8 and 99.7, respectively. Bitdefender returned 2 false positives during the entire period, while Avira came up with 6.

***False positive (the lower, the better) is when an antivirus software falsely identifies a clean file (or URL) as malware-infected.

In the AV-Comparatives’ Malware Protection Test, which was recently held in March 2018, both software once again received the highest ADVANCED+ award, because of their impressive (and same) protection rate of 99.9%. Bitdefender returned 2 false positives in the test, while Avira rang the false alarm only once.

Overall, both Bitdefender and Avira detect all kinds of malware at near-perfect precision.

Winner: It’s a tie

Bitdefender vs Avira: Which Software Puts Less Impact on System?

If a security product is resource-intensive, it can have a negative impact on the performance (or speed) of your computer – especially if your computer is not advanced.

I will once again look at the most recent independent lab tests to find out how much impact both Bitdefender and Avira put on system performance.

The experts at AV-Test measure the average influence of a security product on computer speed while carrying out a few common computer tasks, such as downloading/installing applications, visit websites, copying files. The impact of each security product is calculated in terms of system slowdown it caused on a standard and a high-end PC.

Here are the results of the test with Bitdefender installed:

Here are the results of the test with Avira installed:

Avira's performance test result when conducted on Windows 10 by AV-Test on Jul-Aug 2018

Both software were awarded a perfect 6/6 rating in the ‘Performance’ category.

The experts at AV-Comparatives’ do a Performance Test, which is quite similar to AV-Test’s study. Several common computer operations are executed, and each product is given an impact score (the lower, the better) based on its performance in the test.

Bitdefender was among the few products that were given the highest ADVANCED+ award in the test, because of its impressively low impact score of 6.7. Avira, on the other hand, had to settle for the second-best ADVANCED award, as its impact score was relatively high, at 15.6.

Overall, it can be said that Bitdefender is slightly better than Avira in terms of the impact on system performance.

Winner: Bitdefender

Bitdefender vs Avira: Which Software Offers Better User Experience?

Now, let’s see which of the two software is better in terms of user experience.

First, let’s go over the Bitdefender Interface.

The new Bitdefender 2019 software interface is sleek and modern – in colors of white and dark grey. In the left rail, you’ll find Dashboard, Protection, Privacy, and Utilities (arranged in a vertical menu), along with quick links for Notifications, My Account, Settings, and Support.

Dashboard is the first thing you see when you open the interface. It shows your protection status (with either a green checkmark or a red warning sign), along with buttons to access different modules, like the VPN, the Safepay browser, and more. You can also add a widget of your choice to the main screen.

Protection, Privacy, and Utilities tabs contain relevant features/tools (and their settings). You can switch between different windows while viewing details in the main window.

The name of the Bitdefender plan you’re subscribed to is shown in the title bar.

Now, let’s delve into the Avira interface.

Avira’s interface used to be slightly outdated and monochromatic back in the day, but it has improved a lot (though it still seems a bit complicated) — thanks to a major facelift that took place earlier this year.

It is now bright and airy – in colors of green and white. Like most security software, there’s a vertical menu on the left with five tabs: Status, Scan, Modules, Quarantine, and Activity.

Status window is where you land on when you open the software. You’ll see the ‘Your Computer is Safe’ message written next to a green checkmark if everything is safe. This page also shows whether advanced protection modules (like Real-World Protection, Firewall, etc.) are active.

Scan window lets you run different types of scans, while Modules contain advanced features/tool (and their settings). If a file is identified as malicious, it will appear in Quarantine window. Activity tab is self-explanatory.

Link for Settings and Feedback are available at the bottom-left corner.

Overall, Bitdefender offers a better and more intuitive user interface than Avira.
