Comodo Antivirus is the most polarising antivirus product in the computer security industry. It is loved by the enthusiasts for the multiple levels of protection that it provides, the configuration options supported by this program, the HIPS feature called Defense+ that intercepts each action performed by files and programs, the Virtualization feature called Sandbox that automatically runs a doubtful application in a virtualized environment, and Cloud protection. But, these advanced technologies bring some downsides as well. HIPS makes the program very talkative, something that most users don’t like. Sandbox may automatically run a legitimate program into a container, and there can be problems of False Positives. Anyway, these are secondary issues. The defence provided by Comodo is almost impenetrable.
