Bottom Line

Avira’s free antivirus software can protect computers and mobile devices from malware threats, including worms, viruses, Trojans, and spyware. For free software, it is pretty good, but the paid version, Avira Pro, offers more comprehensive protection including real-time anti-ransomware protection and priority customer support.

In terms of effectiveness, AV-Test, an independent testing company, has consistently found Avira software to be very successful at providing sufficient protection. Avira Pro, which was last tested in June, was found to be 98.8% effective against zero-day malware attacks (attacks from viruses that are previously unknown) and 100% effective against widespread malware that was discovered in the previous 4 weeks.


Speedup Pro allows users to:

  • Optimize startup processes to maximize system efficiency
  • Monitor running processes and close down those draining system resources
  • Fine tune disk optimization for performance, to maximize space, or both

Avira Antivirus Pro features:

  • Real time anti ransomware detector to prevent threats even before they are logged by researchers (based on file pattern behavior)

Ease of Use

Avira free antivirus is easy to use - just download it and follow the prompts for installation. The dashboard is fairly straightforward and the antivirus settings are easy to tweak. The settings can also be adjusted to suit how often you would like your computer scanned.

While the free antivirus software is easy to use, some users report being unable to access certain websites unless they sign up for Avira’s paid version. While this is not the norm, and most users can access all sites, they will still be served ads for Avira’s paid version from time to time.

Avira Pro, the paid antivirus software, is also easy to use. Purchasers receive free tech support and a secure web browser. Pro scans email attachments, constantly updates its database of malware signatures, and blocks known malicious websites. All this is done automatically, but users can also adjust the settings to their own preferences - for example, turning on or off Real-Time Protection, Firewall, Web Protection, Mail Protection and Game Mode.

When something is not right, a red exclamation point will appear next to the issue on the dashboard, which alerts users that they should run a scan or adjust their settings. The software will usually prompt the user toward the correct course of action.

The main issue with Avira, however, is that it can slow down normal computer operation, especially when running the full computer scan. This may be the only downside, especially for people who need a fast-operating system.

Value for Money

As far as a free antivirus goes, Avira is obviously great value for your money. Its anti-malware has consistently scored high results in tests run by independent companies. However, the protection is decidedly basic. This means that all of the features you receive with Avira Pro - anti-ransomware and anti-phishing software, device control, identity protection, safe banking and shopping, and data privacy - are missing from the free version.

At $35.99 per year (for 1 device), Avira Pro is a bit more expensive than its competitors, but the protection you get is top-quality. Avira Pro has consistently scored high on the tests run by AV-Test. In short, while it does cost a few extra dollars, you are receiving an excellent product.

Help & Support

Users who download the free version of Avira antivirus have access to Avira’s Help pages, customer forum, a threat landscape, and security wordbook. Free consultations with tech experts are also available. However, to receive premium customer support via phone and email, users must provide a license number, which is only given to paying customers.

Help pages and customer support are offered in English, German, and Japanese.

User Experience

The free version of Avira antivirus is easy to install. Upon installation, you will also be offered a number of other free Avira products, such as a VPN, system speed-up, mobile security, password manager, software updates, and more. Installation takes a few minutes, and once installed, a little Avira icon will appear on the bottom right of your screen. You can then perform security scans and receive alerts when a suspicious website is blocked.

Avira Pro, the paid version, has a similarly easy installation. While some users have reported that it slows down their computer operations, independent testing has shown that Avira software scans internet files fairly quickly, and is on par with most of its competitors, including Norton and McAffee.

Speedup Pro is also a very straightforward product for users to come to grips with. The quick scanning functionality allows users to initiate a deep system scan for performance issues by clicking on just one button. After that it runs through the system registry, files, and folders in minutes automatically suggesting optimizations to free up space and speed up the computer.

Review in Short

Avira free antivirus offers good, basic protection against malware, but for more comprehensive protection, Avira Pro is the better option. Both products can operate on Windows, Mac, Android, and iOS devices, but only Pro includes anti-ransomware and anti-phishing software, device control, identity protection, safe banking and shopping, and data privacy. While Pro is a bit more pricey than its competitors, the price difference is not significant if you are looking for quality protection and accessible customer support. Users that also want to take advantage of speedup optimizations should check out  Speedup Pro which, for a relatively small monthly fee, can help users ensure that their PC is running free of clutter across both the Registry and the filesystem.
