: A complete virtual operating system environment that allows you to browse the web or run applications without leaving any traces on your physical machine.
: Uses a cloud-based scanner to identify new threats in real-time, ensuring protection even if your local virus database is not yet updated. Performance and Usability
For advanced users, the Defense+ module (Host-based Intrusion Prevention System) was the primary selling point. Version 6.1 offered an unparalleled level of customization. Users could define exact rules for every single process on their computer—dictating which files an app could read, which registry keys it could modify, and which other processes it could spawn. This version struck a perfect balance between usability and control. It offered "Safe Mode" learning capabilities, where it would remember the behavior of trusted installers, reducing pop-ups while maintaining a high security posture.

Comodo Internet Security has always been an "all-in-one" package. Version 6.1.276867.2813 is no exception, bundling four critical shields: Version 6
The crown jewel of CIS 6.1 was its Sandbox technology. In an era where many competitors offered sandboxes as a separate, clunky tool, Comodo integrated it directly into the real-time protection. When an unknown application attempted to execute, CIS 6.1 would run it in a virtual environment (the Sandbox). This meant that even if the application was malicious, it could not write to the actual hard drive or modify system files. To the virus, it looked like it was infecting the system; to the user, the system remained pristine. Upon reboot, the sandbox was flushed, and the infection never actually occurred.
The sandboxing component was the heaviest; launching Chrome inside the sandbox took 3-4 seconds longer than native. However, given the security benefits, most users accepted this trade-off.
