Comodo Free

Comodo provides a free antivirus application for home users that incorporates real-time scanning for internet security. Comodo employs a dual-scanner strategy, which includes a proactive malware protection scanner, a sandboxing tool, and a spyware scanner.

Comodo Complete Antivirus

Comodo Complete Antivirus is the premium version of Comodo’s product. It includes everything from the free version as well as a firewall, web filtering tool to prevent access to harmful websites, and a secure purchasing function.

Comodo Complete Antivirus costs $29.99 for one PC per year or $39.99 for three PCs. Mac and Linux versions are also available for the same pricing as indicated above.

Comodo is the less expensive of the two providers, but it does not have as many functions as Avira. Avira’s premium version contains first-year savings that bring the price down to a level comparable to Comodo’s.

Effectiveness against malware

Are Comodo and Avira’s malware scanners effective? I tested the efficacy of on-demand and real-time scans against a variety of malware test scenarios. The findings will show how successfully each application defends against dangers obtained via the internet, as well as how they cope with typical infections and threats like trojans.

Real-time scanning results 

I will download a variety of virus test files from EICAR (The European Institute for Computer Antivirus Research) to assess antivirus performance. The first test I’ll run will examine how well the real-time scanner works with four EICAR files.

Two of the EICAR files were in a zipped folder, and the other two were unzipped. As seen in the table below, both programs performed well.

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

Avira performed well in my real-world testing, but not perfectly. Avira’s real-time scanning banned all three active files and three of the four EICAR files.

Avira eicar

It accepted one EICAR file in a ZIP folder, but it refused the file when I tried to extract it. Comodo Eicar file Comodo’s real-time protection stopped everything at the moment of download, demonstrating that both Avira and Comodo are effective at protecting against real-time attacks.

On-demand scans

If you’ve ever had an antivirus product installed on your computer, you’ll be acquainted with the on-demand scan features. On the AV dashboard, there is usually a button labeled ‘Run Scan.’ This is an on-demand scan, which means you get to pick when it scans the files on your computer. These system scans can also be scheduled to run when your computer is not in use.

On-demand scans are designed to examine your system and detect any viruses or malware that may already be present on your device. To do this, I disabled real-time scanning and downloaded the malware files to my device to check whether the on-demand scan could detect them.

I had four EICAR files and three live malware files downloaded onto the PC for this test. After that, I conducted on-demand scans to check how successfully they discovered dangerous files.With its on-demand scan, Avira discovered three of the seven files on my PC.

Eicar results

Because Comodo does not enable me to disable real-time scanning in its software, I am unable to obtain malware samples from the internet while Comodo is installed.

One last thing I wanted to look at was how thorough each antivirus’s scan was on my PC and how long it took to finish the scan. When compared to other antivirus applications I’ve tried, Comodo and Avira both had rather speedy complete scan times. Comodo checked 495,365 items in 24 minutes. Avira examined 612,851 files and was only slightly longer, taking just 29 minutes to finish.

I reviewed third-party antivirus lab findings for Avira and Comodo from AV-Test and AV-Comparatives to confirm my own malware testing were delivering an accurate picture.


The Real World Protection Test and the Malware Protection Test are the two major tests used by AV-Comparatives. One looks at real-time protection, while the other looks at on-demand and offline protection, which is similar to my own experiments. These studies are carried out on a far greater scale than I am capable of using many more viral samples.

The most recent AV-Comparatives Real World Protection Test was held between July and October of 2021.

The test matched 17 antivirus software companies against a collection of 743 internet-based threats.

Avira was able to defend against 99.2% of threats and detected just one false positive.

A false positive occurs when an antivirus tool marks a file as a possible danger when it is really innocuous. A high number of false positives irritates users because they generate unneeded alarm and disruption.

The Malware ProtectionTest measures how effectively an antivirus product identifies threats that are already on a device’s hard drive rather than being downloaded from the internet. The most current malware protection tests, which were conducted in September 2021, 10,020 recent and prevalent malware samples were used.

Avira’s offline detection rate was 91.6 percent, online detection rate was 95.3%, and online protection rate was 99.98 percent. It triggered four false alarms throughout the test.

Comodo has not been tested for real-world or malware protection by AV-Comparatives.

AV-Test Results

AV-Test has two primary tests. The first is security against newly found zero-day threats, while the second is defense against known malware that is already pervasive and ubiquitous and was detected in the past four weeks.

Comodo was last tested in July and August 2019 and showed 100 percent success against 0-day real-world attacks in both months. In both July and August 2019, Comodo earned 100 percent protection in the test to identify widespread and common malware.

Avira was most recently tested in September and October of 2021. In September, Avira provided 100 percent protection in the test, and in October, it provided 99.5 percent protection. In the widely used malware test, it achieved a score of 99.9 percent in September and 100 percent in October.

Based on my testing, it’s evident that both Comodo and Avira worked well in real time, blocking all of the malware threats I threw at them. Comodo’s on-demand scanning is more difficult to validate, and test results from independent laboratories are not as readily available for Comodo.

Impact on PC performance

Is it Avira or Comodo that has the most impact on PC performance and speed? I’ll monitor how much system resource use rises during malware scans to find out. The table below displays the results of a fast scan.

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)

After my Avira performance testing, I saw a 5 percent increase in memory use during a fast scan.

There was also a 5 MB/s increase in disk usage and a 23 percent increase in CPU demand. Comodo saw a somewhat intense spike in CPU use, but a decline in memory utilization and a relatively moderate increase in disk utilization of 22 MB/s.

This table displays the results of a thorough scan.

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)

Avira’s CPU use rose throughout the entire system scan, from 9 percent before the scan to 39 percent during the scan. Memory consumption increased by 7 percent, while disk utilization increased by 139 megabytes per second. Comodo’s CPU usage increased by 81 percent. Disk consumption climbed dramatically as well, rising from 25 MB/s to 2006 MB/s, but memory utilization fell by 4 percent.

I examined the most current available lab tests to see how AV-Comparatives rated Avira and Comodo’s performance. AV-Comparatives’ test measures how fast a PC can do routine activities while running antivirus software. The following tasks were evaluated 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 current PC performance data was gathered in October 2021.

Avira was scored as extremely fast in seven of the tests; only its performance on file copying on the first run was evaluated as poor.

Although Comodo was not tested, performance data was available in AV-antiviral Test’s performance tests, which function by assessing the speed of typical operations while the AV software is operating.

Comodo received a 5.5 out of 6 overall performance grade in the most recent AV-Test results.

Because there isn’t much data from the laboratories, I can only rate it based on my own experiments and the data I collected. Overall, I found Avira to have a smaller impact on PC performance.

Comodo vs Avira conclusion

In conclusion, I liked the performance of both Avira and Comodo and I was impressed with both providers’ results in my own real-time malware tests.

Comodo is cheaper than Avira, though it does fail to excite with its extra features which are limited and fairly basic. There’s also a lack of recent data from independent labs available for Comodo.

Avira offers more useful extra features and has a number of product tiers for users to choose from, therefore I make it my choice in this comparison.
