Is your Antivirus doing a great job for you?

Most Antivirus software battles threats they know, not new ones they've never encountered. This strategy leaves open a window of vulnerability from unknown threats that can last for hours or even days.

Comodo Windows Antivirus has a better approach. It's based on the concept of prevention, not detection. Our Windows Antivirus Advanced software features groundbreaking Defense+ technology that efficiently closes this window by treating unknown files seeking access to your PC's critical resources as potentially harmful. Defense+ automatically isolates such files so they can't harm you or your PC.

5 key secrets why Comodo Windows Antivirus is different

  • Cloud-based scanning delivers superior protection against the very latest threats
  • Intelligent protection automatically sandboxes unknown and suspicious files
  • Easy to use interface lets you install and forget.
  • Isolation of all suspicious files eliminates the chance of PC contamination
  • Constantly updated with the latest virus signatures

No free software anymore

The premium protection of Comodo is worthy to have where you get features that are far more advanced than the free programs.

No regrets while renewing

I’d get Comodo every single time since it is so budget-friendly and provides me the protection I expect. I renewed mine a few days ago and Comodo rocks.

Frequently Asked Questions (FAQ)

Why do I need Antivirus Software installed on my PC?

A virus can be absolutely devastating to your PC's health. They can slow your computer to a halt, delete important files and applications, and even make your computer unusable.

What is "quarantine protection"?

When Antivirus finds what it thinks can be a virus, it immediately puts the possible virus in a quarantine state where it can't do any damage. It's extra protection from the trickier viruses.

Will programs run OK in the Sandbox?

Yes. Applications in the sandbox are run under a carefully selected set of privileges and will write to a virtual file system and registry instead of the real system. This means untrusted (but harmless) applications have the freedom to operate as usual while malicious programs are prevented from accessing or infecting your computer. This provides smoothest and most secure user experience possible.

Is it free for business users too?

Yes. However, enterprises looking to implement Internet Security on large networks of workstations would benefit from the centralized management capabilities of Comodo Advanced Endpoint Security.

So why should I use this Antivirus?

Our Antivirus download features top-notch antivirus protection, for free! Real-time scanning, online updates, quarantine protection, total virus deletion...it's all here.

What do you mean by 'personalized protection'?

Antivirus lets you schedule scans for viruses whenever it's most convenient. It does the same thing for updates on the latest viruses.

Do you offer any upgrades?

Yes. Comodo Internet Security (including Antivirus) is available in Plus and Pro versions – featuring 24 hour per day Live Support, TrustConnect and the Comodo Virus-Free guarantee.

Do programs stay in the Sandbox forever?

No – the sandbox is the first part of a trust decision engine. After an unknown application has been placed in the sandbox, Internet Security will also automatically queue it for submission to Comodo labs where it will be analyzed by our technicians. If it is found to be harmless then it will be added to the global safe list that will be downloaded by all Internet Security users in the next round of updates. Once it is added to the safe list, the application will no longer be run in the sandbox by Internet Security. If it is found to be malicious then it will be added to Comodo's list of malware signatures and will be deleted after the next round of updates.

How does the Antivirus protection work?

Just click a button when you'd like to scan for viruses. When Antivirus detects one, it kills it. Dead. Gone.

What is 'Secure Shopping'?

Comodo Secure Shopping provides unbeatable security for online banking and shopping sessions by running your favorite browser inside a security-hardened virtual environment which is isolated from the rest of your computer. This creates a threat resistant tunnel between you and your target website which cannot be attacked by other processes running on your computer. Secure Shopping also features memory-scraping prevention, remote takeover protection and independent SSL certificate authentication to deliver the next-generation of security for online transactions.
