Comodo Free Firewall is a Windows application that offers users complete protection against browser-based threats.

The free firewall features a user-friendly interface with a single scan button and file dropper. Users are able to drag and drop entire directories for scanning, providing them the assurance that their file system is safe.

Moreover, the free version includes an automatic daily scanner that can continue to monitor threats in real time. The software uses prevention-based security to stop malware before it becomes a problem in the system.

Interestingly, the free software also employs a patented Auto Sandbox Technology. The virtualized environment allows you to install an untrusted program in an isolated environment to test them out.

The firewall remembers what softwares are allowed to operate on your machine, changing its alert hierarchy in an intuitive and automatic way. Since the software is cloud-based, it uses deep-scan analysis to detect malware transferred through internet downloaded files.
