Avira Antivirus Review: A Short Summary

Cybercriminals are always inventing new ways to break into your computer to steal money or personal info they can blackmail you with. Using a good antivirus is essential to stop these attacks.

Avira Antivirus is one of the leaders in cybersecurity. Some of its many benefits include:

  • Excellent malware protection
  • Blocking phishing and infected sites
  • Data and identity protection
  • Powerful cloud-based AI
  • Low resource requirements

Avira Antivirus has a subscription option for every budget (from one month to three years). And there’s also a free option that’s almost as good as Avira Pro.

Avira Antivirus is a virus scanner that protects internet users against malware attacks. It keeps your identity, money, and personal information safe at all times. Their new anti-ransomware feature stops unknown threats in their tracks. Avira is a German software company that was founded over 30 years ago. Since then, it has grown into a market leader in antivirus products. However, it’s still relatively small compared to Kaspersky, Bitdefender, Avast or AVG.

Avira recently backed its antivirus with comprehensive security packages, complete with a VPN, browser protection, software updates, password management, and free system optimization.

In this review, we’ll test Avira Antivirus across the board, including its free package and Avira Antivirus Pro. How will their protection, speed, and ease of use fair against our critical eye? You can read all about this and more in our extensive review below.

Avira Packages and Prices

In addition to their free version (Avira Free Antivirus), Avira offers three paid packages with various features.

Avira Antivirus Pro’s Features

The table above already specified which options Avira Antivirus Pro has to offer. The advantage of Pro over the free version is that it offers protection against ransomware. This version won’t bother you with advertisements, and it will give you access to customer service. Apart from that, there are no major differences between the Pro and the free version.

There are a number of features missing from Avira Antivirus Pro, while they are included in several other virus scanners, such as McAfee or Intego. Features like the vulnerability scanner aren’t included, for example. The vulnerability scanner allows you to identify the weak points in your system and thus provides additional protection against hackers.

Avira Antivirus Pro also doesn’t have its own firewall. Firewalls are essential when you want to prevent hackers and malware from reaching your computer. Nonetheless, Avira’s firewall manager can help you optimize the firewall built into Windows, called Windows Firewall.

Avira Free Antivirus Features

There are free virus scanners that are almost as good as their paid versions. However, free virus scanners often have several disadvantages. Consider, for example, annoying advertisements, privacy risks or unwanted browser messages. Free virus scanners sometimes also fail to provide basic protection. You might be wondering, is this the case for Avira Free?

In terms of protection, Avira’s free software, Avira Free Antivirus, is almost as good as the paid version, Avira Antivirus Pro. However, the free version offers no protection against ransomware. Avira Free Antivirus also isn’t equipped with a separate email scanner that checks email attachments for malware and infected links in advance. Nonetheless, the virus scanner does of course offer protection when you try to open malicious attachments.

Virus scanners are often provided for free by producers of antivirus software for marketing purposes. Consequently, Avira Free will occasionally bombard you with popups offering you great deals to get you to switch to the paid version. The free version also regularly tries to convince users that the paid version is necessary to solve certain problems. See the example below:

Avira Free Version Ad

The advertisements and popups are major drawbacks of the free version. The only way to get rid of them is to purchase Avira Antivirus Pro.

Security: How Well Does Avira Antivirus Protect Your Computer?

What about protection against the latest viruses, spyware, Trojans, and malware? Can Avira’s virus scanner recognize active malware and detect phishing? That’s what we’ll be detailing in this section.

Virus detection

Once you’ve installed Avira, the virus detection feature will work all by itself. The virus scanner automatically scans your computer. Avira also offers the option to perform a quick or full manual scan at any time. You can manage these scans yourself, meaning you can decide how often the scan should run.

Avira’s virus scanner offers protection against ransomware and detects viruses, spyware, and Trojans. Infected files will be repaired, and infected sites are blocked. Avira also blocks phishing attacks.

Cloud-based technology

Avira uses the latest cloud technology to provide the best virus protection. When Avira spots a suspicious file, it’ll check it while it’s still in the cloud. This means that most malware detection and analysis won’t take place on your computer. Your device is connected to the global cloud-based threat detection system. Furthermore, since Avira only fights malware on its own servers, it can keep its methods secret.

Hackers won’t be able to figure out what Avira knows. Because of this, Avira is always one step ahead of them. Furthermore, low-resource cloud-based technology makes Avira a light virus scanner that won’t slow down your computer.

Avira Antivirus’s security score

We were impressed with Avira’s security and have calculated a security score for Avira Pro based on research by AV-Comparatives.

According to AV-Comparatives’ tests, Avira scores above average in blocking malware. Only 0.4 percent of the test attacks managed to bypass protection. This is below (and therefore better) the average of all providers tested, which was 0.8 percent.

The tests also looked at false positives. These are harmless files that are wrongly classified as malicious. Only one false positive was detected with Avira Pro. This is well below the average of 8.3.

In our tests, Avira Antivirus is one of the best in the field when it comes to security. There are only a few providers that score better in this regard. For example, Kaspersky protects against 99.9 percent of all threats, with no false positives.

The great security mark in combination with the low number of false positives results in a security score of 9.0 for Avira.

Privacy: How Does Avira Handle Your Data?

Avira states that they don’t just protect users against malware, viruses, and other threats, but also keep users’ personal data safe. This means that user data isn’t shared with third parties, such as governments or advertising firms.

As a German company, Avira has always been subject to one of the strictest data protection laws. This is because, in Germany, privacy protection is seen as one of the most important civil rights. Rules that protect against the misuse of personal data are included in the German constitution and in the Bundesdatenschutzgesetz (i.e. the German Personal Data Protection Act).

Avira declares that they adhere to applicable data protection legislation, in particular the German Telemedia Act (TMG) and the European General Data Protection Regulation (GDPR). For privacy, we, therefore, give Avira a 9.0.

Ease of Use: How User-Friendly is Avira Antivirus?

Anyone should be able to use a virus scanner without difficulty. The installation should be easy, and in principle, the virus scanner should be able to function by itself once installed. In this section, we’ll look at Avira’s ease of use.

Avira’s website

Avira’s website is very user-friendly. At the top of the home page, you can select the antivirus software of your choice. You can choose between the free version, Avira Free Antivirus, and one of the paid Avira Antivirus packages. On the website, you’ll find a short description of each version. You’ll be able to download the chosen software with just one click. Still in doubt about which version to choose? Feel free to consult the detailed comparison of the various packages that can be found on their web page as well.

Avira Antivirus Free Download
First, we tested Avira’s free version. This version is very easy to install. You just need to click the “Free Download” button to start the installation.

How do I install Avira Free Antivirus?

You can install Avira Free Antivirus by following  these three steps:

  1. Run the installation file. Double-click the downloaded file.
  2. Confirm and click “Yes” in the dialog box to start the installation.
  3. Follow the instructions on the screen. This only takes a few minutes.

During the installation of Avira Free Antivirus, various other tools are automatically installed as well. Programs such as Software Updater, Phantom VPN, System Speedup, and Safe Shopping are added to your system automatically without asking you for confirmation first. If you don’t want these unnecessary extras, you’ll have to remove them manually afterwards.

After installation, you’re asked whether you want to perform a smart scan. If you say yes, Avira Free will immediately start the first scan. During this scan, files will be updated and the computer will be scanned for viruses. This all happens automatically.

Avira Antivirus Pro’s installation process

Installing Avira Antivirus Pro is very quick and easy to do as well. The only possible drawback is that the available payment methods are limited, as you can only pay by credit card or PayPal. If you use the latter, your account will automatically be linked to the email address of your PayPal account once your payment and installation are complete. If you pay for someone else or if you purposefully use a different email address for your PayPal account, this could cause issues.

Avira software

Avira Antivirus works on laptop, smartphone, and tablet and has been developed for Windows, Mac, Android, and iOS. Avira Free even reached our top 3 best free antivirus for Mac. The software is available in twelve languages. To change the language, click on the “settings” icon in the top right corner of the screen (the one that looks like a cogwheel).

Avira’s software has a clear user interface. On the start-up screen, it instantly shows the “Status” of your antivirus protection. You can also see when the last update was carried out. Moreover, you can click the option “Smart scan” to instantly start a smart scan of your system.

The virus scanner itself is also very user-friendly and separates its scan results into three sections: security, privacy, and performance. Green ticks indicate that all is well. Any issues are also clearly displayed.

Avira’s customer service

If you have an Avira Antivirus Pro subscription, you can make unlimited use of Avira’s customer service. When you log into your Avira account on the website, simply select the option “Support.” To receive support, you need to complete three steps:

  1. Choose between “technical support” or “payments and licenses questions”.
  2. Indicate which product your question relates to.
  3. Complete Avira’s contact form.

The contact form is automatically linked to the email address of the PayPal account with which you completed your payment. As mentioned earlier, this can be inconvenient. Support is offered in a number of languages: English, German, Portuguese, Spanish, French, and Italian. After completing the contact form, you’ll receive a standardized email stating your query will be answered as soon as possible. When we contacted Avira’s customer service, we received an email response the next day. The speed of this service definitely impressed us.

Avira’s free version doesn’t offer customer support. By checking email addresses, the system recognizes premium users and prevents free users from receiving customer support. Users without a paid subscription will get a message stating they aren’t entitled to that service. They’ll be presented with advertisements for Avira’s premium products instead. Nonetheless, you can of course consult the extensive FAQs on the Avira website. Furthermore, you’ll probably be able to get clear answers to your questions by referring to the videos and useful images available on the website. Unfortunately, there’s no live chat function.

In conclusion, the comprehensive and clear FAQ page in combination with the lack of customer support with Avira Free Antivirus brings us to a 7.0 for Avira’s customer service.

Final assessment for usability

We were pleased with Avira’s ease of use. The antivirus program is easy to install and both the software and the website are very comprehensive. However, the advertisements shown in the free version can be quite annoying, although buying the premium version will easily solve this. That’s why we reward Avira with a 7.0 for ease of use.

Avira’s Speed and System Load

Many will agree that protection is more important than speed, but it’s still preferable when a virus scanner is reasonably fast so you don’t have to wait for hours for a scan to be completed. We ran both a quick antivirus scan and a full scan with Avira Free and Avira Pro, the speed results of which are provided below.

Fast scans versus comprehensive scans

A smart scan takes just a minute with both Avira Antivirus Pro and Avira Free Antivirus. In both versions, the smart scan only scans the most vulnerable areas of the computer. A thorough scan took us about 30 minutes and scans the entire system for viruses. Such scan times are decent and will probably be perfectly acceptable to most users.

The above scan times may vary from user to user and can depend on the number of files on your computer.

System load when running in the background

In addition to speed, it’s also important to look at system load. Virus scanners can overload systems and take up a large part of your CPU’s resources. This can drastically slow down your computer. Slow computers after installing a virus scanner are a major annoyance for many users. Having said that, you might wonder: does Avira slow down your system as well?

We tested the effect of Avira’s virus scanner on our system load. When Avira is running in the background, the processor utilization is 0%. In other words, users won’t notice the difference in computer performance. The maximum RAM usage when running in the background is around 58 MB. During a full scan, the processor’s utilization goes up to 26% with peaks as high as 30%. While performing a fast scan, working memory usage is 64 MB. During a full scan, this goes up to 180 MB. Interestingly, there is no noticeable difference in system load between the free version and the paid versions.

The decent scan times along with the low system load result in a 7.0 for Avira’s speed and performance.

Final Verdict: Is Avira Antivirus a Good Virus Scanner?

AdvantagesDisadvantages

The free version, Avira Free Antivirus, provides good protection.The free version doesn’t offer customer support.
Uses the latest cloud technology for the best virus protection.The free version has annoying advertisements.

We calculated a final score by looking at security, speed and system load, privacy, ease of use, and customer service. Security counts most strongly in our score and has a 0.5 weighting. Speed and system load come next with a weighting of 0.2. Privacy, ease of use, and customer service each have a weighting of 0.1.

Below are the scores for Avira per component:

  • Security: 9.0
  • Speed and system load: 7.0
  • Privacy: 9.0
  • Ease of use: 7.0
  • Customer service: 7.0

We arrive at a final mark of 8.2.
