What is Comodo Internet Security?

Comodo Internet Security is a free antivirus and free firewall that optimizes and protects a PC from all malicious codes that can destroy a computer. Unlike most other antiviruses, e.g., 360 Security, CIS offers all its protective features for free.

The Comodo antivirus is also integrated with the Comodo firewall, so it also offers prevention as much as it provides a defense against malware.

Host-based intrusion prevention

The Comodo antivirus has a host-based intrusion prevention system called Defense+. HIPS protects your computer from unknown malware. It restricts the actions of unknown programs, preventing them from accessing folders, files, settings, the Windows registry, and other computer resources.
