As you can see, Avira provides users with more generous features including a VPN service, privacy, performance and security apps. In addition, you can get these feature-limited tools for free.  

Antivirus protection

Just like the majority of antivirus systems, Kaspersky combines a digital-signature matching engine with heuristic monitoring. Utilizing these two methods, the antivirus system is capable of detecting both, known and previously unseen malware threats. All suspicious items are sent to cloud-based Kaspersky's servers for further examination.

Kaspersky has detected all the threats we have installed in our test PC running Windows 10. 

The independent AV-TEST[5] testing lab tested Kaspersky in its the most recent tests. Kaspersky demonstrated one of the best malware detection rates and detected 100% of both, zero-day malware attacks, including web and email threats and 100% of widespread and prevalent malware.

When it comes to Avira's antivirus defenses, the company uses the same detection techniques for all of its Windows products that include a traditional malware scanner that searches for the digital signatures or suspicious icons to match already known malware signatures and heuristic monitoring which looks for suspicious behavior and analyzes code. Avira collects all new and unusual behaviors to Avira’s cloud-based servers, on which all the icons are carefully investigated.

The antivirus engine includes Real-time Cloud scanning which examines unknown files in the cloud anonymously from over 400 million its customers. Users can easily turn off the sharing feature.

It is worth to mention that Avira demonstrates almost flawless malware detection. It was tested in the latest antivirus tests by the independent German-based lab AV-TEST. Avira got the rating 6.0 out of 6.0 and detected 100% of zero-day malware attacks, including web and e-mail threats. When it comes to detection and prevalent malware, Avira managed to detect 100% and 99.9%.

Both providers offer superior malware detection results.

System-performance impact and scans

According to our test results, Kaspersky Anti-Virus can slow down your system by a maximum of 10 percent, which is a perfect score.

In addition, AT-TEST[5] also rated Kaspersky 5.5 out of 6.0, as it delivered better results than the industry average.

  • Slowing-down a system while launching popular websites – 36% (19%)
  • Impact on a system while downloading frequently-used applications – 0% (1%)
  • Impact on a system while launching standard software applications – 9% (8%)
  • Impact on a system during the installation of frequently-used applications – 13% (25%)
  • Impact while copying of files – 4% (3%)

The first scan took about 30 minutes, the subsequent scans were finished in less than ten minutes, which is pretty fast. In addition, its quick scan only took about 2 minutes to complete. During the full scan, the OpenOffice tool finished about 30% slower than the baseline, which is in the middle.

When it comes to performance results, Avira is very light on a system and it demonstrates a lower influence on computer speed than most of its competitors.

Avira also was tested by AV-TEST[5] that rated it 6 out of 6.

  • Impact while launching popular websites – 9%.
  • Impact while downloading frequently-used applications – 1%.
  • Impact while launching standard software applications – 5%.
  • Impact while installing frequently-used applications – 26%
  • Impact while copying files – 8%.

Researchers at Reviewed by Pro also pointed out that one of the strongest sides of Avira is low resource usage. The full system scan took an average of about 1 hour and 40 minutes. The quick scan took only 1 minute and 30 seconds which is very quick compared to other similar products.

To sum up performance results and scores, Avira provides better results and does not drown the system.

User Interface

Kaspersky has a modern design and the user interface is easy to use. However, despite this, there is an issue with the navigation. If you move away from the Home screen, you will not have many choices – to use another feature, you will have to press ‘Return’ and only then you can choose another option.


Avira’s interface is very bight and open. As usual, the main window is half-size and cannot be expanded, but can be moved around. The main window indicates the device’s performance and provides the list of other Avira applications installed, such as Software Updated, Phantom VPN, System Speedup, Password Manager, SafeSearch Plus and Software Updater.


Customer support

When it comes to Kaspersky, users can easily contact the support team via My Kaspersky, email or phone. In addition, for those, who prefer looking for information themselves are provided with a very informative support webpage that includes Knowledge Base, How-to videos, forums, and FAQs.

Avira also has an informative support page for those, who prefer looking information themselves. Avira also provides customer support via phone and email. Users also can fill out the form to get Avira's technicians to go back to them. We couldn’t say that it is extremely easy to reach customer support at Avira. 


In order to test the popularity of the brands, we have checked the OPSWAT Windows Anti-Malware Market Share Report[6] that lists ten of the most popular names in the Internet security industry. According to the report, Kaspersky Lab is the seventh with 6.65% of the market share, while Avira appears at the bottom with 4.5% of the market share.

Other popular names in the report include Avast, McAfeeMalwarebytesBitdefenderESETWebrootSafer Networking Ltd with SpyBot Search & Destroy,  Avira, and Symantec with Norton.

The final verdict

As you can see, Kaspersky antivirus is also one of the best choices in the market. The antivirus system detects 100% of malware, however, its system performance impact in the latest tests is only average. 

All in all, we rate the latest Avira Antivirus one of the best in the industry. It is a great application if you have a device that you want to keep running fast and malware-free. Avira offers flexible plans and a decent set of tools.

Final thoughts

To sum up, we recommend users Avira. The antivirus application was tested by the most recent tests and demonstrates decent malware detection rates and trustworthy performance scores. In addition, it is also very easy to navigate and manage.
