Quick answer: Comodo Antivirus is still offered in October 2026 by Comodo Security Solutions, Inc., in a free version and a paid Complete Antivirus version. Comodo’s site listed Complete Antivirus at US$29.99 a year for one PC or US$39.99 for three PCs when we checked. Comodo’s main idea is containment: unknown programs run in a sandbox, so they cannot change your system until they are judged safe. Comodo does not currently appear in the main independent lab tests from AV-TEST and AV-Comparatives, so there are no recent lab scores to compare it with rivals.
This review is based on Comodo’s own website and on the published test lists of the main independent labs. We have not tested the software ourselves. An earlier version of this article reported a full-scan time of “1 hour and 20 minutes”, a two-second slowdown in loading websites and a 40% slowdown in a Handbrake benchmark, and said Comodo “sets the bar high for the industry”. We have removed those results because they had no named, dated source.
Free Antivirus vs Complete Antivirus
As of October 2026, per Comodo’s antivirus site:
| Version | Price | What it adds |
|---|---|---|
| Comodo Free Antivirus | Free | Basic protection, including Defense+ (which protects critical system files) and Auto Containment |
| Complete Antivirus | US$29.99 a year (1 PC) or US$39.99 a year (3 PCs) | Secure Shopping for online banking and shopping, web filtering and unlimited product support |
The paid version is sold together with Comodo’s firewall; Comodo’s page calls it Comodo Internet Security and describes a 2025 edition with a redesigned interface, support for Intel’s Threat Detection Technology and faster scanning on Windows through Microsoft’s BypassIO. The original article referred to “Comodo Antivirus Advanced”; Comodo now uses the names Free Antivirus and Complete Antivirus.
Features Comodo documents today
- Auto Containment (sandbox): unknown files run in an isolated environment where they cannot damage your system. The original article described this as running untrusted programs in a sandbox, including a virtual desktop.
- Default Deny and Defense+: only known-good programs run freely, and critical system files are protected. This is the “default deny protection” the original article mentioned.
- Cloud-based antivirus and whitelisting: files are checked against Comodo’s cloud database of known good and bad files, as the original article explained.
- Firewall and host intrusion prevention (HIPS).
- Application Control: lets you lock down which programs can run, as the original article described.
- Game Mode: suppresses or postpones alerts and background tasks while you play. The original article highlighted this.
- Scans: on-demand, on-access and boot-time scans, plus heuristic detection. The original article described Quick, Full, Custom and Rating scans.
- Secure Shopping (paid version): runs your browser in a secure container for banking and shopping.
- Other platforms: Comodo’s site also lists antivirus products for Mac, Linux and Android. The original article noted a free Mac antivirus and a Linux tool.
Comodo’s page still lists compatibility with Windows 7, 8, Vista and XP. Microsoft no longer supports those versions with security updates, so an antivirus alone cannot make them safe; move to a supported version of Windows if you can.
Independent test results
The original article said users found Comodo passed protection tests “in flying colors”, without naming a test. In October 2026:
- Comodo was not among the 19 products in AV-Comparatives’ 2025 consumer test series.
- Comodo did not appear in AV-TEST’s Windows 11 home-user tests from October 2025 to August 2026.
That does not mean Comodo protects badly. It means there is no recent independent score to compare it with products such as Norton, Bitdefender or ESET, which are tested regularly. Comodo’s containment approach is designed to stop unknown threats rather than only detect known ones, but you would be relying on Comodo’s description of it.
Comodo’s own comparison page compares its price and features with older versions of rival products and cites Wikipedia as its source. Treat it as marketing rather than an independent comparison.
Who makes Comodo?
Comodo Antivirus is made by Comodo Security Solutions, Inc., according to the copyright notice on its website. Comodo says it develops cyber security products for businesses and uses the same technology in its home antivirus.
Who Comodo suits
- Good fit: experienced users who like a free antivirus with a firewall, sandboxing and detailed controls, and who are comfortable answering security prompts.
- Think twice: if you want an antivirus with recent independent lab results, or one that needs little attention. Windows already includes Microsoft Defender Antivirus, which is tested by both major labs.
