Each day we hear about a new threat to the computer in the form of virus or a new spyware. Sometimes antivirus software is not able to detect all the types of threats. ThreatFire provides a behavior based monitoring tool to protect the computer from malicious programs like virus, Trojans, spywares, key loggers etc. It is not a substitute for the antivirus program but when used together, it provides an additional level of security.

ThreatFire protects the computer by detecting malicious behavior like capturing keystrokes, changing startup entries or registry etc. It works by continuously analyzing the behavior of the processes running on the system and will throw an alert when it detects some suspicious activity. Normally most of the anti-virus uses ‘signature’ based detection and must have the signature of the virus before it can be detected properly. Once it detects a threat, it will check it against the database for a quick identification. It can protect you against a lot of threats like spyware, adware, key loggers, viruses, worms, Trojans, root kits, buffer overflows and other malwares. The program requires no configuration and it can work instantly after install. It is not a memory hogger and consumes around 10 MB of memory. Occasionally you will do encounter some false alarm but that is to be expected from a behavior based monitoring system. It also provides info about the processes that are currently running on the system.

The program is free and you should use it along with your regular anti virus program. A paid version of the program is also available but there is not much difference between the two. It works on Windows 2000, XP, 2003, Vista.
