ThreatFire features innovative real-time protection technology that provides powerful standalone protection or the perfect complement to traditional signature-based antivirus programs. ThreatFire's patent-pending ActiveDefense technology offers protection against both known and unknown viruses, worms, trojans, rootkits, buffer overflows, spyware, adware and other malware. It uses behavioral analysis to hunt down and paralyze threats that are too new or too clever to be recognized by traditional "signature-based" antivirus software. Powerful protection against zero-day and emerging threats.
