How Virus Protection Works with Comodo Defence + Technology? Comdo's trademark Defence + technology, in combination with Host Intrusion Protection System (HIPS) goes beyond the traditional blacklist of programs. Even if a suspicious file type is able to evade the initial blacklisting, Comodo's Defence technology isolates any unknown and potentially hazardous file to run within the Sandbox environment. The Sandbox Technology aids the user to continue working uninterrupted while treating the threats in a quarantined zone. This predictive functionality embedded in Comodo virus protection software gives it a competitive edge over other security software, most of which identify only the known threats.
