Threatfire's new beta now supports 64-bit! Key new features: * Smarter Alerts, Less Questions – patent-pending technology * Support for Windows Vista 64-bit * Updated threat detection technology "PC Tools has recognized that traditional scanning techniques are becoming a secondary defense to sophisticated malware techniques. User feedback has also indicated that most users install ThreatFire as an added layer of protection in additional traditional anti-virus scanning software. As a result ThreatFire 4.1 no longer includes an anti-virus scanner. Users requiring an anti-virus solution should download PC Tools AntiVirus, a free solution for Windows" "One of the changes we made, is that TF now does cloud lookup for the black and white lists as well as using the default black and white lists on your system. Basically you could delete the dbs on your system, and still not lose the benefit of black and white lists. Let us know what you think." - those are some quotes from the mods over at pc tools beta forum.
