Besides AVG AntiVirus FREE, another solid free security option for Windows is Avira Free Antivirus (sometimes also misspelled as Advira) from Germany. How does it compare to Avast Free Antivirus? Both products are very similar with great sets of features. However Avira is scoring lately as #1 antivirus in the independent tests, especially in the virus and malware detection and low number of false positives.
On the other hand Avira is much more aggressive in terms of up-selling to paid versions and the pop-up offers are extremely annoying. Of course Avast is using them too, but not that frequently. Anyway let’s take a closer look on both products and see which one is the best.
Avira has also recently started pushing a new product called Avira Free Security Suite which combines all Avira free products – Antivirus, Phantom VPN (500 MB/month), Password Manager, System Speedup, Scout (browser) and Software Updater. Obviously the whole free suite requires much more system resources, so we recommend staying with the basic Free Antivirus and adding components you need.
Feature Comparison Table – Does Avira Offer More Than Avast?
Avast definitely offers more in terms of advanced features and tools like Home Network Security for scanning router vulnerabilities, Browser Cleanup for scanning browser extensions, or Software Updater for scanning outdated software in your system. Avira is purely an antivirus, which isn’t necessarily a bad thing. Both products offers an option to create a bootable disc with the latest antivirus version to clean your system when it doesn’t start.

The only feature which has Avira on top of Avast is the Firewall management. It’s not a built-in Firewall, it’s just providing front-end management for the default Windows Firewall. What is nice about Avira is that it doesn’t require user to register/activate the product (as Avast does). So you can install and use the product for free forever.
Impact on the System Resources – Which Product is Lighter?
We have measured the impact on the system resources using two ways:
- How long does the computer to boot into Windows desktop while the Avira or Avast is installed
- How does the computer performs in various areas (CPU, Graphics, Memory and Disk operations) while the Avira or Avast is installed
In the boot time test where less is better, it took only 28 seconds (in average) to load Windows desktop when Avira Free Antivirus was installed. Same operation took 30 seconds (in average) when Avast Free Antivirus was installed. Default boot-time without any antivirus solution in place took 28 seconds. So according to our testing, Windows loads faster with Avira. Actually Avira has no delay or impact on the system start up.
Avast vs. Avira – Performance Test Results
In the second area we have tested computer performance in various areas and impact of the Avira or Avast on the results. Avast scored 2,138 points and Avira got even slightly more – 2,147 points. The default performance without any antivirus installed was 2,156 points. So the overall impact on the system performance is really low for both products, but again Avira is the winner here.
Final performance test results are highlighted on the chart below. You can clearly see the difference between no antivirus and Avast or Avira present. Please note the vertical axis ‘Performance Score‘ is not starting from 0, but from 2,116 to clearly show the small differences.
You can find more details about how we tested in the ‘Additional Notes‘ section at the end of the article.
User Interface – Is Avast Easier to use Than Avira?
Avast user interface is really nice and clear. There is only one main action leading to Smart Scan, which runs all seven Avast scans: compatibility, viruses, outdated software, browser add-ons, router issues, performance and weak passwords. The green button ‘UPGRADE‘ (or ‘ACTIVATE‘) leads to comparison table of Avast Free Antivirus and Avast premium product (Avast Internet Security).
The status is also indicated by color, when green obviously means ‘You’re protected’. The left menu is easy to navigate and structured in four groups – Status (home screen), Protection, Privacy and Performance. At the bottom part there is usually an up-sell banner which is quite soft and does blend nicely within the Avast interface.
The whole Avast interface is quite large (1010 x 674 pixels) and will not work on 800 x 600 pixel screens. On 1024 x 768 pixel screens it takes almost whole monitor space.
Avira user interface looks like a typical Windows application with the default window style and top menu. On the first sight the interface is much more busier with lots of buttons and settings. Looks like the main action on the status screen is ‘Upgrade Now‘ which leads to up-sell page. Also it’s not properly aligned as each box has a different height and box ‘Looking for Tech Support?‘ is sort of a flying around the interface.
Similar to Avast the status is also indicated by green colors and the message ‘Your computer is secure‘. The components ‘Web Protection‘, ‘Mail Protection‘ and ‘Game Mode‘ are available only in the paid versions. What is nice about the interface is that there is no up-sell banner in the whole user interface. The only way to up-sell within the interface is the green ‘Upgrade Now‘ button.
You can start system scan or update directly from the main page although it’s not much visible. Settings are accessible through the cog wheel next to each item or quite unusual from the menu under ‘Extras‘.
Localizations/Translations – Is The Product Available in my Language?
Both Avast and Avira are available in plenty of languages, of course for free. But Avast offers many more.
Avast languages (46): Arabic, Belorussian, Bengali, Bulgarian, Catalan, Chinese (simplified), Chinese (traditional), Croatian, Czech, Danish, Dutch, English (United States/United Kingdom), Estonian, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Malay, Norwegian, Persian, Pirate talk, Polish, Portuguese (Brazil/Portugal), Romanian, Russian, Serbian, Slovak, Slovenian, Spanish, Swedish, Thai, Turkish, Ukrainian, Urdu and Vietnamese
Avira languages (12): English, German, French, Spanish, Italian, Dutch, Portuguese, Turkish, Russian, Japanese, Chinese (simplified), Chinese (traditional)
What is really annoying is that you can’t change language manually within the Avira product. It’s somehow automatically detected based on the system settings.
Popularity – Which is the Most Popular Free Antivirus? Avast or Avira?
The better product is, the most users it has. It’s simple as that. However it’s not easy to say which is most popular antivirus, if Avast or Avira. For expressing popularity we are using several, publicly accessible methods: official websites, OPSWAT reports, CNET Download.com ratings and social media.
1. Official Sources
According to official website, Avast is protecting more than 400 million users worldwide, but that also includes AVG products. Last publicly available number was 230 million users before the AVG acquisition. Avira is not stating user numbers publicly anymore, before they usually claimed to have over 100 million users. In the recent tweet Avira stated over 500 million users are protected by their technology. Based on these reliable claims, Avast has at least twice more users than Avira.
2. Antivirus Vendor Market Share by OPSWAT
OPSWAT is regularly releasing reports about the antivirus market share. Data are based on the OPSWAT GEARS software installed on the client machines. According to the latest report from June 2017, Avast is dominating the worldwide market with 20.48%. Followed by ESET with 13.14% and McAfee with 9.42%. Avira is at the fourth position with 7.73%. It is also important to mention Microsoft for some reason is not included at all.
3. CNET Download.com Ranking
Download.com by CNET is the World’s most popular download portal. According to its popularity rankings, Avast has more total downloads – more than 406 million, while Avira has ‘only’ 147 million. Avast is also leading the the most popular downloads list for the recent week, while Avira is not even in the top 20.
However these stats are influenced by each vendor download model. Avast is sending visitors from Avast.com to Download.com while Avira is downloaded from their own internal servers which are not counted to Download.com statistics.
Both vendors have great editor’s rating of 4 stars (meaning excellent), but Avast has better user/community rating of 4.5 stars versus Avira’s 4 stars.
4. Number of Fans on Social Media Networks
Another way how to measure product/company popularity is by the number of fans/followers on social media networks like Facebook and Twitter. Avast is leading on Facebook with 4.1 million fans vs. Avira’s only 1.2 million. On Twitter the difference is even bigger. Avast has 181 thousand followers and Avira only 19 thousand.
Independent Labs Test Results – Will Avira Protect You Better Than Avast?
If you are looking for more advanced comparison of antivirus protection, the best resources are the independent test labs. These labs are regularly performing various tests like how many viruses will get through the antivirus software, or which vendor offers better performance.
In most of the independence tests the winner is Avira, whether it’s the Real Word Protection Test or Performance Test. Avast is usually in the top 3. However Avira usually sends their paid product (Avira Antivirus Pro) for testing while Avast is being tested on the free version.
Selection of the most important and relevant test results is below:
- AV-Comparatives Real Word Protection Test Results (May 2017)
- AV-Comparatives Performance Test Results (May 2017)
- AV-TEST Compare Manufacturer Results
- Virus Bulletin VB100 Avast vs. Avira Comparison Test Results
Respected computer magazine PCMag gave Avast rating of 4,5 stars and Editor’s Pick award in their comprehensive comparison of free antivirus solutions written by security expert Neil J. Rubenking. Avira got only 3,5 stars.
Our current Editors’ Choice products for free antivirus utility are Avast Free Antivirus and AVG AntiVirus Free. Both get very good scores from the independent labs, and in our own tests as well. Both include some useful bonus features.
