ThreatFire AntiVirus Free Edition

ThreatFire offers real-time prevention of virus and malware infections by identifying suspicious behavior (“zero-day” events) as it happens, before malicious code installs itself on your PC.

ThreatFire does do some things very well. It seeks out rootkits, heuristics-based threats, viruses, worms, trojans, spyware, adware, keyloggers, and buffer overflows. The software real-time protection didn’t noticeably slow down our computer, and the customizable advanced settings were excellent. Users can pick and choose their preferred trusted processes and create rules for detection, such as scanning for SCR files created by an e-mail client. You can also avail yourself of the scheduler, and create a system restore point before moving threats into quarantine. Working as a complement to your currently installed antivirus, ThreatFire has improved markedly in the past few years.
