Protect your PC against viruses, rootkits, buffer overflows, and malware.

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. Since PC Tools--formerly known as CyberHawk--bought the program, it has made some dramatic and noticeable feature improvements.

ThreatFire 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. The IntelliScan took about 15 minutes on our machine, but it didn't lock us into scanning mode. We were still able to check out other panes in the ThreatFire interface.
