You get Protection that is Ironclad
Comodo's free antivirus provides the best protection from malware instances, virus infection and suspicious hidden files. It includes reliable cloud based, quick scanning, continuously updated with the latest malware information from around the globe.

Unlike any other antivirus, Comodo protects you against threats that have not even been identified yet by security experts because only verified files are allowed to be run your system.

Here's how we do it:
Comodo Antivirus uses a unique multi-layered approach that ensures that your computer will not be harmed by malware.

  • Known malware are identified using a "blacklist" signature file and deleted or quarantined.
  • Known valid files are identified as safe using a "whitelist" of valid files and run safely.
  • Intrusion Detection and Behaviour Analysis (Heuristics) are used to identify potential threats from other files and deal with them.
  • Any file not verified as safe will only run in a safe isolated system area called the Sandbox where it can do no harm to your files or operating system.

All that for free, plus a user friendly interface. You can also upgrade to our subscription version and receive world class customer support and the industry's only virus free guarantee.

Don't just take are word for it.
Comodo Antivirus is the winner of the CNET Editor's choice award and has been rated Perfect for Protection by the independent test lab AV-Test Labs.

What makes Comodo Antivirus for Windows 8 better than other suites?

Comodo Antivirus for Windows 8 utilizes the core features of antivirus and firewall combined with the exclusive Defense+ and Auto Sandbox technology. Comodo is the only vendor who provides these trademark features to offer best protection. The Windows Antivirus program also uses Default Deny protection which prevents virus infection by allowing only authorized programs to run. Defense+ defends against malicious threats while Sandbox mode runs suspicious files in an isolated environment to secure system registry.

Are programs stored in Sandbox forever?

No. The auto sandbox mode is a temporary virtual system environment created to test run files and programs before they access your original operating system, files and registry. Comodo Internet Security for Windows 8 offers a feature to send suspicious files to Comodo AV labs for detailed analysis. Safe and authorized programs are added to the whitelist while threats join the blacklist of programs. The sandbox is recycled and ready to perform a new set of operations after completing each task.

Can business users make use of the free version?

Yes, it is possible. However, to get comprehensive protection for a large network of computers and to secure important valuable data, we recommend Comodo Endpoint Security Manager (CESM).

Can I customize installation to choose either firewall or antivirus?

Yes, you can. End users have the freedom to use Comodo Internet Security for Windows 8 as per their individual requirement. Install antivirus for Windows 8 or firewall as you require. You can choose to check or uncheck components during the installation process.

How does Sandbox technology work and how does it protect me?

Auto Sandbox technology is an exclusive feature of Antivirus for Windows 8. Comodo Internet Security for Windows 8 comes bundled with the feature which creates an isolated, virtual system environment where all suspicious files and programs will be executed in trial mode before being granted access to your actual system. This prevents any virus or bug from modifying, corrupting or deleting actual data in your computer. The innovative feature provides stronger protection than traditional antivirus and any malicious files found will instantly be added to the blacklist.

Will programs run properly in Sandbox mode?

Yes. The Sandbox is a virtual, isolated extension of your actual desktop integrated with Antivirus for Windows 8. Every suspicious file or program will be executed in this mode with a limited set of privileges. It will be tested thoroughly and confirmed safe before it is granted access to the actual registry. The analysis runs in the background without interrupting your daily activities. Safe programs are given permission while virus, bugs or trojans are permanently denied access to your PC.
