    What is Avira?

    Avira is one Antivirus softwarethat has not had it easy in recent years. Often the software came pre-installed on computers. This did not cause much joy, especially among PC users, as the antivirus is sometimes equipped with a lot of advertising. However, Avira has learned from past mistakes and improved its virus protection. In addition, Avira now also offers features for privacy and anonymity. A VPN is even included in the free version.

    Free vs. Chargeable

    Avira Free is a free version of the antivirus, which already offers solid protection in real time against viruses and malware of all kinds. In our test in particular, we were able to discover all types of malware with the free version. Thanks to the large database and the powerful virus scanner, Avira Free offers everything you need for basic protection for your computer. In the free version

    The free variant scores above all with the following properties:

    • Very good virus scanner

      Avira Free adapts to your digital needs and protects you and your data from all possible threats from the Internet. And that in real time! The virus scanner delivers a strong performance and was able to convince us in our test.

    • Very large database and regular updates
      Thanks to the large virus database, malware etc. have no chance of getting onto your device.

    • (Limited) VPN
      Thanks to the built-in VPN, you have the option of protecting yourself on the Internet. With the help of the VPN, the IP address is anonymized so that you can surf undisturbed without leaving any traces.

    Avira Free Antivirus

    Of course, the free version only has limited functions. Even if Avira Free is already a very good virus protection, apart from the scanner, the updates and the limited VPN there are no other features. This is precisely why it is worth taking a look at the paid versions.

    This is missing from Avira Free:

    • No protection with ransomware
    • Limited functions which are visible in the user interface but cannot be clicked (and if you click on them, you get annoying advertisements)
    • No web protection
    • No protection against phishing Webseiten
    • No protection for e-mail attachments
    • Hardly any extra features
    In short: The free version is ideal for testing the virus scanner. However, if you want to completely protect your device or network, you should fall back on the premium versions.

    Avira Antivirus - The packages

    As I said, Avira Antivirus not only offers its antivirus as a free version, but also in two premium versions. If you need a good virus scanner with additional functions, you should definitely opt for one of the paid options. There are two versions:

    Avira packages


    Avira Internet Security for Windows

    The premium protection package from Avira offers all-round protection for a Windows device. So if you only have one computer that you want to protect, you can be content with this package. The following features are included in this version:

    • Blocks malware and infected sites
      As soon as you come across fake sites, Avira will automatically block them.
    • Password manager
      Thanks to this feature, you can have strong and unique passwords created for you in no time.
    • Very good firewall

    • Automatic driver updates

    • Real-time protection, web protection and ransomware protection

    However, Internet Security also has the following Disadvantages:

    • No customer support
    • No TuneUp tools
    • Limited VPN
    • Protection for only 1 device
    • No mobile support

    So if you would like to optimize your device and protect your smartphone or tablet at the same time, you should use Avira Prime.

    Avira Prime

    This version includes all the functions of Internet Security and more. Especially if you don't want to do without tuning tools, this package is worth purchasing. It must also be said that in this version you can protect up to 5 devices at the same time. So if you have more than just a Windows PC at home, Avira Prime is the right choice.

    Avira Prime Dashboard

    Advantages this package:

    • All the features of the Internet Security Suite
    • VPN with unlimited data volume
      Especially if you value privacy and anonymity on the Internet, you should use this version. Because only here you get unlimited data volume and unlimited data traffic with the VPN.
    • 40 premium optimization tools

    • Android: From Android 4.1 (Jelly Bean) - only in Avira Prime!
    • Phone: iOS 10.3 or higher - only in Avira Prime!


    Avira compatible

    In our test, Avira was able to score in every respect. Even the free version offers a strong virus scanner with real-time protection. However, if you want premium features, we recommend you Avira Prime to take a close look at.

    However, we have that as positive felt:

    • Strong virus scanner
      The virus scanner was able to correctly recognize all phishing websites and removed malware we had placed without any problems. The large virus database also ensures that you are protected from the latest threats.
    • Real-time protection and password generator
      If you need a strong, unique password, you can easily create it with Avira. An absolute plus, because nowadays you need complicated passwords for every website.
    • VPN included
      The VPN is unlimited in Prime. The Windows version could catch up here, because a VPN is definitely important. With Avira Prime, however, the VPN is unlimited - streaming and anonymous surfing are guaranteed.
    • Over 40 optimization tools
    • Simple user interface
      The program is quite easy to install and use. You don't have to search long for further configuration settings.
    • Refund warranty
      There is a 30-day money-back guarantee for the premium packages
    • Speed ​​during a scan
      The computer continues to run normally during a virus scan. The internet speed wasn't slow.
    • Virus scanner speed
      The virus scanner's performance is definitely not the best. During one Rapid tests took AVG around 13 minutes, For one Complete scan of our computer took us just under 1 hour. That is still within the scope.

    We have that as negative felt:

    • Protection for mobile devices only with Avira Prime
      Neither the free virus scanner nor the Internet security offer protection for your mobile devices.
    • Price-performance ratio
      Avira Prime is an all-in-one package that contains a lot of functions, but the price of € 99,99 is very high. This only applies if you want to protect up to 5 devices. The price increases if you want to protect up to 25 devices.

    customer Support

    There is nothing wrong with customer support - provided you buy one of the premium versions. Then you get a VIP customer support. In any case, in the free and paid version you have the option of contacting support via e-mail. Avira also offers a support website with a fairly comprehensive knowledgebase. However, you can reach support for certain questions - the response time is only mediocre. In our test, we had to wait 3 days before we received a detailed answer.


    Avira does not have the best reputation there is in the antivirus market. In our test, however, we found that Avira has done bravely. With the strong antivirus scanner and the numerous tools that are available in the paid versions, Avira can definitely compete with the market giants. Avira Free is also a solid scanner, but hardly offers any additional functions. As for the protection, we can rightly say that it is very solid and very good. All in all, good virus protection.

    AviraTotal Protrection test report & experience 2020
    All in all, a solid virus scanner that is ideal for Windows users. What we also liked is that you can buy the antivirus protection per month - you don't have to commit yourself for at least a year.
