Comodo offers a free version of their antivirus. They also provide three paid packages. The Comodo Internet Security Complete, internet Security Pro, and Comodo Antivirus Advanced.

For many years, Comodo Antivirus was recommended by cybersecurity experts and enthusiasts due to the impressive list of features it provides. Some users may consider Comodo Antivirus as too complicated due to this reason alone. But, I think that Comodo Antivirus is one of the easiest to use.

If you need a highly configurable antivirus with lots of cybersecurity features and tools, but easy to use and implement, then this is for you.

Comodo Antivirus and Comodo Internet Security are free to download.

The Comodo Antivirus Free

Comodo Antivirus Free comes with impressive security features making it one of the most secure and top-performing antivirus products in IT security. Comodo Antivirus Free also comes with active measures against viruses, trojans, malware, spyware, rootkits, adware, and system vulnerabilities.

Not many free antivirus software offers this much of antivirus security modules.

Comodo Antivirus Free is also available for Linux and macOS. The officially supported Linux distributions are Ubuntu, Fedora, and OpenSUSE.

Features of the Comodo Antivirus Free

Antivirus Cloud based behavior analysis

This feature is known as the Valkyrie. Comodo is using a cloud-based behavior analysis system to identify even the newest threats. This methodology is extremely effective.


VirusScope is a unique antivirus feature and it is useful for local PC analysis and helps the users of the PC to identify and fix issues caused by the malware infestations.

Host Intrusion Prevention System

The Host Intrusion Prevention System or HIPS is providing the capability of monitoring the computer and preventing malicious attacks from entering it.

Quarantining threats

Antivirus measures taken by Comodo makes sure that all the suspicious programs are quarantined and stored in a separate environment  (sandbox) to monitor its behavior until Comodo is sure that this program is not malware.

Default Deny Approach

Comodo Antivirus also prevents all files by default from entering the system until it is sure that these files are harmless. To get this done, Comodo is using cloud-based virus scanning technology.

Cloud-based white-listing

This feature helps the user to quickly identify harmless and legitimate files.

Game Mode

Game mode turns off unwanted notifications and does not alert the user about anything unless it is absolutely necessary to do so.

Comodo Antivirus Advanced

comodo antivirus features
comodo antivirus features

comodo antivirus featuresThe Comodo Antivirus Advanced comes with many advanced features and includes many impressive features such as the Auto Sandbox Technology and host intrusion prevention.

Another plus point is that Comodo Antivirus is highly configurable.

Comodo Antivirus Advanced can be used for business purposes as well. But, Comodo is recommending the use of Comodo Advanced Endpoint Security in case of implementing Internet security on a large network of workstations due to its centralized management capabilities.

AV-Test tested Comodo Antivirus back in December 2018 and it achieved an admirable 100% protection against zero-day attacks such as phishing and malware payloads.

AV-Test also gave the Comodo antivirus a  6/6 rating for virus protection, 5/6 for performance, 5.5/6 in usability. 16.5/18 rating in total.

In August 2019, AV-Test gave Comodo Internet Security a rating of 100% protection against zero-day attacks such as malware attacks, malware payloads, and web and email threats based on real-world testing.

Detection of widespread and prevalent malware discovered within four weeks was also rated at 100%.  So it scored a rating of 6/6 for protection against cyber threats. The performance score was 5.5/6. Usability was rated at 5.5/6. So the total rating was 17/18.


Features of the Comodo Antivirus Advanced

True Decision Engine

Auto Sandbox Technology

This feature provides smooth functionality without interrupting the user to observe the behavior of unknown files. To do this properly without having the possibility of malware infestation, Comodo keeps the unknown files or suspicious files in a separate virtual environment where these files are monitored for any behavioral change. These files are not allowed to enter the system until Comodo Antivirus is sure that these files are not harmful.

Applications in the Sandbox are run under a carefully predefined set of privileges and the internal communications that happen in between the app and the operating system are getting written to a virtual file system and a virtual registry instead of the real system or the real registry.

The Sandbox is the first stage of a trust decision engine.

Internet Security. Cloud-based real-time whitelisting and blacklisting of files or applications.

After the unknown or suspicious files or application has been placed in the Sandbox, Internet Security automatically put it in a queue for submission to Comodo labs.

If it turns out to be harmless or legit, then it is fed to a real-time cloud-based white list and therefore doesn’t run in the Sandbox by Internet Security.

If it is found to be harmful, then it is added to a real-time updating blacklist of malware signatures and therefore will be deleted after the next batch of updates.

This feature ensures that unknown files or suspicious files cannot damage Windows OS, registries, or important user data.

Proactive Defense + Technology

The Comodo Antivirus provides Proactive protection, not reactive protection. Many antivirus software is still using reactive protection methodology, which is kind of out of date. Proactive protection is constantly monitoring the system for suspicious behavior and takes measures to prevent them before these threats could damage the system or user data.

To get this done, Comodo is using a heuristic learning methodology with the help of cloud-based detection systems. The cloud-based detection system is getting updated in real-time without any user intervention.

Cloud-based antivirus protection makes sure that Comodo Antivirus Advanced is detecting even the newest cyber threats without the need to rely on up to date virus definitions.

Comodo is providing constant virus definition updates and you have to restart the computer to make it work properly.

When I tried to download EICAR files, the antivirus quickly quarantined it. The compressed version wasn’t blocked by the antivirus but when the downloaded file was unzipped, it was detected immediately.

When scanning the system, even the compressed files were detected.

These features also offer anti Trojan protection, anti-worm protection, and anti Rootkit protection

Cloud-based whitelisting

Comodo is using the cloud-based whitelisting methodology to update the known list of files and services provided by verified software service providers. Doing so eliminates any chance of falsely identifying legitimate files as a threat as well as saves the resources and time that could others have wasted on taking measures against something completely safe.

Anti Spyware protection

A real-time spyware scanner is detecting malware infections by constantly scanning computer registry files and discs. It also pays attention to the security privileges and access to resources provided for applications and makes sure that the apps are not misusing them.

Doesn’t rely on user input to provide cybersecurity.

Comodo Antivirus Antivirus provides so many advanced features and tools to ensure maximum cybersecurity, but it requires minimal user involvement to do that. Comodo Antivirus Advanced doesn’t rely on user input to decide whether to allow, block, or quarantine unknown or suspicious files or programs. This also provides the user with a much better digital experience with minimal interruptions.

Anti Ransomware protection

The ransomware protection feature is constantly monitoring the system for files and applications for suspicious behavior and is using a cloud-based blacklist to compare the behavior of suspicious applications or files with the signatures of already detected blacklisted cyber threats.

Host Intrusion Prevention System

The Host Intrusion Prevention System or HIPS is a foolproof yet heavily customizable approach to set behavioral rules and restrictions for each and every one of the installed applications. Any behavioral change or suspicious activity is then alerted to the user.

Applications provided by unknown parties and suspicious files and applications are being monitored for any suspicious behavior.

HIPS further provides users with the capability of allowing or blocking certain applications from being in contact with the system.

HIPS is deactivated as default and is recommended only for the experts as allowing a malicious file or program can result in information loss and malware infestations.

It’s better to let Comodo Antivirus Advanced take decisions all by itself as it is perfectly capable of doing so.

Valkyrie sandbox technology

Comodo Antivirus Advanced has its own Sandbox to run suspicious files and programs in a secure environment.

Users can use the Valkyrie sandbox module to run suspicious or unknown files and applications in a safe and separate environment without the possibility of infecting the system as all the application level communications are taking place in between the app and OS are being written to the virtual registries and virtual system rather than being written to the actual registries and files.

Sandbox module can be used to select the browser of your preference to run in a safe and separate environment. This protects the web browser from cyber threats. This also prevents spyware from monitoring user activities.

The virtual desktop feature requires the installation of Microsoft Silverlight to become fully functional. The virtual desktop feature provides a completely isolated environment and uncompromised security against malware and virus threats.


Application Control

This module makes sure that the installed applications are as a matter of fact legitimate and are developed by legitimate vendors.

It also helps the user to lock down a functional but infected system, to operate it, and to navigate it, or fully recover a total unbootable OS from a Live USB device.

The dedicated firewall is powerful and easy to configure. The Comodo firewall provides an extra layer of security for the windows stock firewall. All the files and applications are constantly being monitored to find out whether there are any unauthorized communications between outside parties and already installed applications or background processes.

Both inbound and outbound communications of suspicious nature are blocked to ensure overall system security.

Users are also allowed to whitelist or blacklist applications from connecting to the network.

Using a firewall blacklist option along with parental control feature allows the user to prevent children from accessing age-restricted material such as porn or abusive content.

Gamer mode

The Game mode makes sure that the user is not disturbed while they are running a computer game or a resource-hungry application on the full screen. During this time, all the scheduled scans and unnecessary background processers are kept at bay. This helps the user to experience computer gaming without any disturbances.

Anti Spam protection

The Anti Spam protection feature adds an extra layer of protection to flag spam emails. Nowadays not a lot of antivirus programs offer these features as all the major email service providers such as Gmail, Yahoo Mail, Yandex Mail, and Outlook mastered the art of warding off spam and successfully identifies and flags more than 95% of spam messages.

Comodo Antivirus flags the spam emails and lists them as spam in the title of the message. Users can predefine the anti-spam feature to redirect all the spam messages to a specific folder as well.

Protection for chat and IM applications

Comodo antivirus also offers protection for chat and IM applications to protect the user from phishing attempts. This feature isolates the chat and IMP application processes by adding a layer of encryption to prevent them from communicating with other background processes.

Secure Shopping

Secure Shopping feature enables the user to do credit card transactions without worrying about someone stealing their financial information.

Comodo Secure Shopping encrypts the browser communications thus preventing tracing or hacking attempts.

Secure Shopping also hides all the sensitive online data from other processes on the computer as well. This is done by putting a shield f protection to isolate all browser-related processes to prevent other processes to communicate with them.

This prevents hostile processes from stealing or getting access to browser processes and keyloggers from recording keystrokes or screenshots of the user session.

This feature also detects false SSL certificates and warns if there’s a remote connection to your computer.

Chrome, Firefox, chromium-based browsers, firefox based browsers, and Edge are officially supported.
