PCs are under attack. Viruses. Spyware. Identity Theft. Every day you hear about a new threat. They're coming faster than ever, and they're getting harder to stop.

Traditional antivirus solutions cannot protect you until after they've discovered a new threat and produced a signature to counter it.

ThreatFire is different. It does not rely on signatures, but instead constantly analyses your computer's behavior to detect and block any malicious activity. ThreatFire protects immediately so you know your PC and your valuable data is always secure.
