What Is The Best Free Antivirus?
It is just a one-line answer. The best free antivirus is the one that will stop all known and unknown malware.
Basically, there are three types of files that a free antivirus solution has to handle – known bad files, known good files and the unknown files. The "unknown files" are the greatest culprits. They could be malware of any type - viruses, worms, adware, bots, bugs, rootkits, spyware, Trojan horses, scareware, ransomware, keyloggers, grayware — the list is huge.,Get Complete Protection

The Best Free Antivirus vs. Known Bad Files
Known bad files are malware that has been detected.Antivirus software maintains a definition of the malware in its virus database. The information in the virus database is shared between antivirus solution vendors as part of a collaborative effort. This collaborative effort must be appreciated, as every day thousands of new malware files are released into the wild. Detecting, analyzing, developing a definition and then adding it to the virus database requires considerable effort
When the Free Antivirus engine encounters the "file" it will compare it against its virus database, and if it exists in its database then the antivirus will immediately block and quarantine the detected malware. Based on the system administrator's settings, the malware may be deleted from the system. This is how a typical virus detection and removal takes place. The free antivirus will allow all other files into the system.
The Best Free Antivirus vs. Unknown Files
This is where a traditional free antivirus, (however good it may be) fails. These solutions do not have a mechanism to detect maliciousness in unknown files. These unknown files gain complete access to all the areas of the system and may even travel over the network and infect other connected systems. The entire network will get compromised, with the user being none the wiser. Cyber threats are becoming highly sophisticated. Cybercriminals with appropriate tools can create different strains of existing malware within a short period (even within seconds). And traditional antivirus solutions will not detect these strains.
The Best Free Antivirus is an antivirus solution that provides protection against all new viruses through a default-deny posture. It should allow only safe applications to run, and block/seclude all unknown applications.
The Comodo Free Antivirus solution features a default-deny posture that blocks all unknown files. These files are automatically containerized in a sophisticated virtual environment and their behavior is studied in detail. The malware will unsuspectingly carry out its activities and perform its malicious activities believing that it is affecting the actual system. However, this complete process is virtual. The malicious behavior will be observed and analyzed for a quick verdict. If the file's behavior is harmless then it is allowed into the system, but if it is found to be malicious then it is blocked.
The Comodo Free Antivirus is the best free antivirus solution that offers the only way to stay protected against all unknown malicious files and zero-day threats.
The Comodo Internet Security Suite combines the Comodo Free Antivirus, firewall, and other security solutions to provide complete protection against all types of cyber threats.
