If you’re looking at protecting more than just a Windows PC, both Kaspersky and Avira work with all the major operating systems which include Windows, Mac, and Android devices.

Effectiveness against malware

What are the strengths and weaknesses of Avira and Kaspersky when it comes to malware protection? Is it possible for the live scanner to detect viruses in files that have been downloaded from the internet? Do on-demand scans reveal any viruses on the computer’s hard drive?

To discover this, I devised a series of experiments. This includes downloading four EICAR (European Institute for Computer Antivirus Research) sample files as well as three malicious apps that hide viruses like trojans and adware.

Real-time scanning results 

I began by downloading the four EICAR sample files to observe how the real-time scanner discovered and eliminated them, or even if it allowed the download.

In my real-time tests, Avira worked well, but not flawlessly. All three live files and three of the four EICAR files were blocked by Avira’s real-time scanner.

Avira eicar

It allowed one EICAR file in a ZIP folder, but it rejected the file when trying to extract it from the zipped folder.

Test FileEICAR Sample 1EICAR Sample 2EICAR Sample 3EICAR Sample 4Live Sample 1 (Adware)Live Sample 2 (Trojan)Live Sample 3

The results of the same test using Kaspersky’s software are presented in the table above.

In real time, everything was successfully discovered and blocked by the program. Eicar samples were not allowed, and live samples were erased as soon as they were unlocked and unzipped.

On-demand scans

I used the on-demand scanner to see how well Kaspersky and Avira can detect and remove malware that is already on the PC or attached via an external hard drive or USB.

I disabled the antivirus’s real-time scanning feature for this test so that I could download the EICAR and live samples to my device. I then performed a quickscan before doing a full scan to record the results.

I conducted the quickscan, which is designed to check the most visible sections of your computer rapidly. Avira’s fast scan took 41 seconds, whereas Kaspersky’s took 273 seconds. The quickscan for both vendors were rapid, but also failed to discover any malware. This is not uncommon, most other quickscan tests I’ve done with other antivirus programs fail to find malware during a quickscan.

Avira free Eicar

The on-demand full scans had more success. Avira’s full scan found three of the seven files, however Kaspersky’s complete scan found all malware and removed all EICAR test malware and the three live samples.

The largest drawback was Kaspersky’s lengthy full scan, which took 3 hours and 47 minutes to complete and scanned about 2.1 million files.

Kaspersky came out on top in terms of the depth of its scans. It took 227 minutes to check the 2,100,000 files, while Avira checked significantly fewer files (612,851), but it was far faster, taking only 29 minutes to complete.

Next, I checked the latest independent antivirus lab test results to see how well Avira and Kaspersky performed against a larger set of malware.


The AV-Comparatives Real World Protection Test was last conducted between July and October of 2021.The test pitted 17 different antivirus software providers against a set of 743 internet-based dangers.

Avira was able to protect against 99.2 percent of the threats, whereas Kaspersky was able to protect against 99.9 percent of the threats.

Avira was ranked fourth to last out of 17 antivirus programs. Even if the percentile differences across all of the providers are tiny, they add up to a significant difference in how likely the antivirus program is to be bypassed by malware.

The test also tracks false positives. When an antivirus program flags a file as a potential threat when it is actually harmless, this is known as a false positive.

A large number of false positives irritate the user since they cause unnecessary alarm and disturbance. Avira produced only one false positive, whilst Kaspersky identified none. Both providers performed admirably in this area.

The Malware ProtectionTest evaluates how well each antivirus application detects threats that are already present on the hard drive of a device rather than being downloaded from the internet.

10,020 recent and prevalent malware samples were utilized in the most recent malware protection tests, performed in September 2021.

Kaspersky had an offline detection rate of 84.7 percent, an online detection rate of 87.6 percent, and an online protection rate of 99.90 percent. During the test, it generated two false alarms.

Avira achieved 91.6 percent for offline detection, 95.3 percent for online detection, and 99.98 percent for online protection. During the test, it generated four false alarms.

AV-Test Results

The most recent test data from AV-Test is from September and October 2021. In September and October, Kaspersky received a perfect score against 0-day real-world threats, using 407 malware samples. Another test employing 18,521 samples was undertaken to determine performance against widespread malware detected in the previous four weeks.

In September and October, Kaspersky provided 100 percent protection.

In September, Avira achieved 100 percent protection in the test, and it scored 99.5 percent in October. It received a score of 99.9 percent in September and 100 percent in October in the widely used malware test.

Impact on PC performance

When the real-time scanner is turned on in the background, how do Avira and Kaspersky affect PC performance? How much of an influence does a full system scan have? Is either of these slowing down your PC and interfering with your day-to-day tasks?

To find out, I conducted some tests. The results of the quick scan on system resources are shown in the table below.

Test TypeControl CPU Utilization % (no scan)Control Memory Utilization % (no scan)Control Disk Utilization (MB/s) (no scan)Quick Scan CPU Utilization %Quick Scan Memory Utilization %Quick Scan Disk Utilization (MB/s)Quick Scan Time (seconds)

In my performance tests on Avira, I detected a 5 percent increase in memory consumption during a quick scan. There’s also a five-MB/s rise in disk utilization, as well as a 23 percent increase in CPU consumption. Kaspersky’s CPU consumption increased by 25 percent, memory utilization increased by 3 percent, and disc utilization increased from 12 MB/s to 273 MB/s.

After that, I made a note of the impact of a complete system scan on the system’s resources.

The findings are shown in the table below.

Test TypeControl CPU Utilization % (no scan)Control Memory Utilization % (no scan)Control Disk Utilization (MB/s) (no scan)Full Scan CPU Utilization %Full Scan Memory Utilization %Full Scan Disk Utilization (MB/s)

During the full system scan, Avira’s CPU use increased from 9 percent before the scan to 39 percent during the scan. Memory utilization climbed by 7 percent, while disc utilization grew by 139 megabytes per second.

Kaspersky’s complete scan revealed a significant increase in CPU usage, jumping from 46  percent to 100 percent. Memory utilization increased by 6 percent, but disk utilization climbed from 12 to 316 megabytes per second.

I looked at the most recent available lab tests to see how AV-Comparatives assessed the performance of Avira and Kaspersky. The test determines how quickly a PC can do common tasks while antivirus software is installed. The following list of task were assessed by the lab:

  • Downloading files
  • Browsing websites
  • File Copying: first and subsequent run
  • Installing and uninstalling applications
  • Archiving and unarchiving
  • Launching applications: first and subsequent run

The most recent data on PC performance was collected in October 2021.

For seven of the tests, Avira was rated as very quick; only its performance on file copying on the first run was assessed as slow.

For seven of the eight tasks, Kaspersky was scored as very quick. The only task for which it did not receive a perfect score was launching apps on the first run, despite this it was still classified as fast so most users would not notice any slow down on their PC.

Which antivirus is more user-friendly?

When it comes to user-friendliness, Avira’s interface is designed with simplicity in mind, allowing users to effortlessly navigate and utilize its features. This intuitive design is particularly beneficial for those who may not be tech-savvy, instilling a sense of comfort and confidence in their ability to use the software effectively.

On the other hand, Kaspersky, while also user-friendly, has a more complex interface due to its extensive range of features and settings. These include advanced threat detection, customizable scan options, and detailed security reports, which might be overwhelming for some users who prefer a simpler interface.

Which antivirus has better speed and performance?

When it comes to speed and performance, Kaspersky is a clear winner. Kaspersky’s software is engineered to have a minimal impact on system performance, ensuring that users can run scans and use their devices without experiencing significant slowdowns. This efficiency, as highlighted by independent tests and user reviews, should reassure users about the software’s performance.

While also performing well, Avira tends to have a slightly higher impact on system resources, which can lead to slower performance during scans and other intensive tasks.

Which antivirus offers better user privacy?

When it comes to user privacy, Avira is the champion. Avira, headquartered in Germany, a country with stringent data protection laws, offers users a high level of privacy assurance. Avira’s commitment to user privacy, coupled with its policy of not collecting unnecessary data, should instill a sense of security and protection in users.

Although Kaspersky has robust security measures, it faces scrutiny due to its Russian origins, which raises concerns about potential government access to user data.

Avira vs Kaspersky conclusion

In this comparison, Kaspersky comes out on top. It had the best malware detection results in my tests, picking up all seven test files in its on-demand scan. It offers more functionality than Avira and outperforms Avira in independent AV testing labs by a small margin. In addition, Kaspersky gives substantial discounts for the first year of subscription, lowering the cost of using its software.
