Get Free Antivirus for PC
Most free 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’s free Antivirus software for Windows 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.

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.

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.

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.
