There are different types of malware that are used to attack computers - viruses, ransomware, Trojans, rootkits, worms, spyware, scareware, adware, keyloggers, bots, etc. Each type inflicts a different type of damage. A ransomware would prevent access to the system or encrypt the data; spyware would spy on the activities taking place in the system and steal data; a keylogger would capture the keystrokes (which would allow it to capture sensitive passwords and other credentials); a Trojan misleads users of its true intent; a virus is a type of malware that replicates itself, modifies other computer programs, and inserts its own code.

The Real Danger of Zero-day Exploits
Typical Free antivirus solutions offer the features mentioned above. In the present-day cyber world, attackers target vulnerabilities in computers for which fixes are not yet available. These vulnerabilities are termed as zero-day exploits. Attackers could initiate an attack in the morning and by evening, much before when the antivirus companies have found a cure (a way to block the malware), the damage would have been done. Traditional antivirus solutions are effective only against known malware.
A study of the reports about top free antivirus solutions would reveal that a different solution is recommended by each report. The variation would be based on the criteria considered for the comparison. But not many reports consider the ability to detect and block/remove unknown files.
Default-Deny Security
The Comodo Free Antivirus, which is a part of the Comodo Internet Security Suite, features a default-deny feature that provides protection against the threat of unknown files. It automatically blocks and containerizes unknown files. The behavior of the files is then studied within a sophisticated virtual environment. Based on the behavior, a verdict is reached and only if it is found to be good will the file be allowed into the system; If the file is found to be malware it is deleted.
Comodo Free Antivirus is the Top Free Anti Virus as it is the ONLY solution that provides protection against zero-day threats (unknown malware).
