ESET, a Slovakian internet security firm, was awarded the most successful company in Slovakia in 2008, 2009, and 2010. It has won several awards and accolades for breaking new ground in the field of cybersecurity.

Since 2003, ESET has earned the VB100 award for malware detection more times than any other provider, and it has been approved in every test.


The Avira name has been established since 2006, but the company’s antiviral technology has been in the works for much longer. H+BEDV Datentechnik GmbH, the company’s forerunner, was formed in 1986 in Germany. Avira was bought by U.S. antivirus brand NortonLifeLock in 2020.

ESET vs Avira pricing

There are a plethora of antivirus firms, each of which sells a variety of products. This might make deciding on the best malware protection for you more difficult.

ESET has a large selection of antivirus packages. It provides single-device security for Windows, macOS, and Android, allowing you to cover from one device up to 25.

This starts at $14.99 (GBP £11.01) a year for an Android device and goes up to $59.99 (GBP £44.09) per year for the top-of-the-line package, ESET Smart Security Premium, which includes all of the advanced features. Let’s take a closer look at all of ESET’s antivirus packages.


ESET’s NOD32 antivirus software is the company’s most cost-effective option. This edition comes with a few unique features in addition to strong antivirus protection. The main highlights are phishing protection, cloud-based scanners, ransomware defense, and free customer support.

Avira software’s free edition includes a virus and malware scanner as well as a few restricted supplementary features. There is a VPN, however, it only allows you to transfer 500MB of data each month.

As a result, it can only be used for a few basic tasks that don’t rely on heavy data use. In addition to the free version, Avira provides three premium suites, each of which adds different tools to the main antivirus scanner.

Avira Free SecurityAvira Antivirus Pro (1 device)Avira Internet SecurityAvira Prime
Free$40.00 (GBP £29.37) per year$52.00 (GBP £38.18) per year$114.78 (GBP £84.29) per year

Avira Antivirus Pro

Avira Antivirus Pro is available in three versions and can cover one, three, or five devices.

Protection for one device costs $40.00 (GBP £29.37) per year. It costs $64.00 (GBP £47.01) for three devices and $74.74 (GBP £54.90) for five devices.

Avira Internet Security

Avira Internet Security comes with two additional features: a software auto-updater and a password vault. The annual subscription for this package is $52.00 (GBP £38.18) per year for one device.

Similar to Avira Antivirus Pro, users may cover up to five devices for one, two, or three years.

Avira Prime

The company’s most costly package is Avira Prime where the annual fee climbs to $114.78 (GBP £84.29), but this covers up to five devices. Avira Prime is now available in a family edition that protects up to 25 devices. The yearly charge for the family edition is $149.67 (GBP £109.96).

Effectiveness against malware

While most antivirus companies include other utilities with their scanners, the scanner is the most significant means of determining how effectively it protects against infection.

Malware may be used to steal data and money from hackers while also jeopardizing the victims’ safety and privacy.

To see which of ESET and Avira came out on top, I ran my own tests. I used four EICAR samples and three live samples, including adware and Trojans, to see how effectively each program’s real-time scanner performed.

Real-time scanning results 

When you download files from the internet, a good antivirus program will use a real-time scanner. When you access content from the internet, a decent antivirus application will do a real-time check on the object and stop it from downloading if it appears to be malicious.

This type of proactive defense is critical for preventing infection. All EICAR samples, as well as the three live samples, were blocked in real-time by ESET in my real-time testing.

ESET effectiveness

Avira’s real-time scanning stopped everything, except for one of the IP files, which it permitted to download but then blocked when extracted.

Avira effectiveness

Despite providing adequate protection, I found Avira to be a little sluggish in detecting and removing samples when compared to other antivirus products.

On-demand scans

System scans search your existing files for any possibly harmful apps or documents on your machine. Only entire system scans are possible with ESET’s product, so I couldn’t do a quick scan. I was able to run a quick scan using Avira, which took only 41 seconds to finish and found no viruses or spyware.

In 68 minutes, ESET’s full system scan analyzed over 930,000 files and found all of the hazardous files.

Three of the seven files were detected by Avira’s complete scan, while the others were overlooked. Avira’s full scan took 29 minutes and included 612,851 items. Although it does not go as far as the ESET scan, it takes 39 minutes less to finish.

To back up my results, I looked at how the major antivirus testing labs AV-Test and AV-Comparatives rated ESET and Avira in past evaluations. Both laboratories do testing on a number of prominent antivirus products on a regular basis, providing a complete picture of current and historical antiviral performance.


The AV-comparatives tests that I am interested in are the Malware Protection Test and the Real World Protection Test.

The software’s ability to protect against online threats such as contaminated downloads and illegitimate websites is assessed in the Real World Protection Test.

The most recent information comes from testing conducted between July and October of 2021. In the real-world protection test, AV-Comparatives pitted popular antivirus programs against 743 malware samples.

ESET successfully guarded against 98.9 percent of the threats in this test, with no false positives. ESET was ranked 16th out of 17 top antivirus companies in this test as a consequence of these findings. Avira was rated 13th out of 17 antivirus products for its ability to guard against 99.2 percent of the threats.

The Malware ProtectionTest, which includes instances when malware is already on the disk, was next.

In September 2021, the most current Malware Protection Test was conducted, and ESET came in 16th out of 17 antivirus products evaluated, with a 99.82 percent protection rate. There was one false positive in this test for ESET. Avira has a 99.98 percent protection rate. In this test, Avira found four false alarms.

AV-Test Results

The most recent AV-Test results for ESET and Avira were published in November and December 2021.

In November and December ESET received a 100 percent success score against real-world zero-day threats from AV-Test, which used 330 malware test cases. In another test to see how the program did against widespread malware ESET again scored 100 percent protection in both months.

During the same test period, Avira achieved 100 percent protection in the test for November, and it scored 99.3 percent in December. For the prevalent malware test, Avira scored 100 percent in both months.

Overall the results slightly favor ESET and in particular, the most recent testing data available from AV-Test gives it a perfect score in protecting against both new and well-known malware. This backs up my own test results where ESET again found all the malware files it was faced with.

Impact on PC performance

Antivirus software uses your computer’s resources, such as CPU and RAM, to scan files and check for viruses and malware.

I did a quick scan and then a full system scan to evaluate which had the least impact on PC performance: ESET or Avira.

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)

ESET has no quick scan option so we can’t assess its impact. For Avira, CPU utilization increased by 22 percent during the quickscan. Memory increased five percent, and disk utilization increased from 31 MB/s to 36 MB/s. So overall it had a pretty light impact on the PC’s system resources.

Onto the full system scan results and ESET’s took 68 minutes, and when I examine the total number of files scanned, I see that ESET scanned approximately one million files. The performance test data reveals that ESET had a small influence on CPU and memory consumption, but that disk utilization increased significantly throughout the scan.

During a comprehensive scan, Avira’s utilization of system resources increased.

CPU usage during the full system scan jumped from 9 percent before the scan to 39 percent throughout the scan. Memory use increased by 7 percent, while disc usage increased by 139 MB/s.

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)

I reviewed the most current performance results from AV-Comparatives to see how my findings compared to third-party lab testing data.

The test evaluates antiviral speed and efficiency by determining how quickly commonly used applications and activities react while the antivirus is running. The following are the tasks performed during the test:

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

In the AV-Comparatives Performance test results from October 2021, ESET earned the highest available score for all but one of the tasks listed above. it failed to gain top marks for file copying on the first run, when it was still classed as fast. Avira scored as very fast for all operations except file copying, which was assessed as slow.
