ThreatFire 3 is a free program that detects malicious software based on its behavior. The program requires no configuration so it is easy for anyone to use. When ThreatFire detects suspicious malware it immediately quarantines it, with lower risk malware it asks you what to do.

In our testing ThreatFire successfully blocked all installations of malware that we attempted. The success rate was higher than the well known Spy Sweeper.

The pro edition that costs $29.95, failed to clean up a system that was already infested. However we strongly suggest that you download this excellent security program.
