Why Choose Avira

Avira offers one of the strongest basic antivirus software platforms in the industry and has ranked consistently at the top of independent testing. The software is also compatible with most devices so that you are covered from threats regardless of the operating system.

Paid versions of Avira include document scanning, cloud protection, file repair, and other features that make this antivirus an attractive choice at low costs. Avira lets you customize scans and enjoy real-time protection from malware attacks.

What Avira Offers

Avira Free Antivirus offers basic features, including:

  • Antivirus

  • Malicious phishing URL filter

  • PC optimization

  • Limited VPN

Avira Antivirus Pro includes all of the basic capabilities of the free version, but adds several features with this first level of subscription:

  • Real-time malware protection and file scanning

  • Financial protection for online transactions

  • Ad-blocker

  • Customer support

  • Privacy protection

Avira Internet Security is the second tier of paid subscription and offers all of the features of the previous 2 packages, as well as some added capabilities:

  • Password manager and generator

  • Online account protection

  • Automatic updates

  • System scanner

Avira Prime is inarguably the best antivirus and security package on offer from this company. This premium service delivers AI-driven protection to identify and neutralize malware and ransomware attacks. Other added features include:

  • VIP support

  • Computer cleaner

  • Safe web surfing

  • Access to premium mobile apps


  • Malware

German-based Avira uses artificial intelligence and cloud-based threat detection to prevent and neutralize all forms of malware. A swarm intelligence feature is possible through a worldwide cloud that allows the system to anticipate, analyze, and neutralize threats in real-time. Avira’s software includes numerous additional safety features, including “nightvision” AI learning and PUA Shield, which identifies unnecessary applications buried within legitimate software.

  • Ransomware

Avira uses artificial intelligence and cloud-based threat detection to prevent and neutralize malware in its many forms. The swarm intelligence feature is possible through a worldwide cloud that allows the system to anticipate, analyze, and neutralize threats in real-time. The German-based antivirus provider is a solid choice for protection against ransomware, as its AI learning features are designed to stay apace of developing ransomware and identify potential attacks in real-time.

Other premium features include Game Mode, which allows gamers to maintain game flow and avoid annoying pop-ups and lags, a Power Cleaner to free up extra space on your computer, and other optimization features to enhance functionality. It should be noted, however, that Avira does not offer a number of features common to other antivirus software providers, such as parental controls, spam filters, and a firewall. While Avira is a good antivirus option, it is limited.

  • Phishing

Avira offers anti-phishing protection in both its free and premium products. Avira Free Antivirus works in tandem with a browser extension to automatically display a splash page whenever the user attempts to visit a known phishing URL. The database is continuously updated and based upon reports from users around the world. The same excellent phishing protection is included in all Avira premium products including both antivirus and internet security. 

Ease of Use

Avira is easy to install; just download the application and let the installation wizard navigate the process. Once installed, Avira will run the first scan of your computer to identify any problems. Once the scan is completed, you'll have a general understanding of your computer's health.

Avira has been improved and delivers a sleek interface with a user-friendly experience. Operating the antivirus on any system or device is seamless, a benefit over some other providers.

Detection Rates and Reliability

In independent testing, Avira performs well overall, with high scores heading into 2019. However, in one recent test from AV-Test, results found Avira lagging with 99.4% zero-day malware detection. Nonetheless, other reviews found Avira effective 100% of the time.

With top-quality malware and ransomware detection at the Pro level, Avira consistently performs well, although some users have reported gaps in ransomware protection.

Avira offers a solid, free version that is effective at deflecting malware threats and keeping your computer virus-free. This is, of course, excellent value. The paid versions of Avira antivirus deliver a long list of added features at a good price, but there are other products on the market with better features in the same range.

Help and Support

Avira antivirus offers instant customer support for paid clients. However, customers with the free version can benefit from a range of resources available on the site, including video tutorials and articles. Customer support can be reached via email, social media, or online chat, as well as the ability to set up a scheduled one-on-one support call for more complicated issues.

Avira also hosts a community forum platform where users can discuss specific topics. With all of these resources, users may find the answers they are looking for and not need to contact customer support.

Bottom Line

Avira is a good, basic, free antivirus with several tiers of paid packages featuring more advanced protection. The software performs consistently well in independent malware and ransomware threat containment tests but is less effective at identifying phishing scams than other programs. Game Mode is a unique feature offered at the Prime level that may appeal to gamers.

For a paid antivirus, Avira is highly customizable and does include a wider range of features, but not as many as other antivirus software offerings currently on the market. Some gaps include a lack of parental control, firewall, and spam filter.
