PC Tools ThreatFire

ThreatFire is an application designed to protect your computer against
malware such as trojans, spyware, rootkits, keyloggers, and buffer
overflows by intelligently detecting and blocking behavior consistent
with that of malware. It does this by constantly monitoring your
system, and analyzing programs and process activity. Whenever it
detects any unusual process or activity, it will display an alert with
further information on the threat. If it is a known threat, then it
will automatically quarantine the malware and no further action is
required on your part. If the threat is unknown, or new, then
ThreatFire will display an alert and prompt you to Allow or Quarantine
the process. All alerts provide detailed information to help you make
an informed decision.

What's New

Security software alerts can cause confusion about the appropriate action to take (block, allow etc). ThreatFire 4.7 reduces this confusion by significantly minimizing both the number and the type of alerts that require you to make a decision. This is made possible using two new techniques:

· Behavior profiling: patent pending technology which groups threats into families based on common traits or characteristics of the threat — similar to the way authorities profile criminals. This technology makes ThreatFire capable of catching hundreds of variants of malware derived from the same original threat and helps you to make a more informed decision about any malicious activity on your computer.
· In-the-cloud techniques: potential threats are also verified against in-the-cloud black/white lists that are regularly updated to determine how they should be handled. This approach means ThreatFire asks fewer questions; requiring fewer decisions from you. Only on rare occasions when those potential threats are not identified through ThreatFire’s behavioral analysis and its in-the-cloud database, you will be displayed an action alert (yellow alert) for you to make a choice as to whether to block or allow the threat.

· These technologies combine to provide the most up-to-date threat protection while intuitively handling threats.

· ThreatFire 4.7 incorporates patent-pending technology to provide greater accuracy in detecting real threats and a greater ability to avoid classifying legitimate programs as potentially malicious (known as a false positive). The method that ThreatFire uses to determine the legitimacy of a program has been completely re-engineered in an effort to further reduce false positives. This new method of rating will ensure that ThreatFire’s alerts include more accurate and relevant information about potentially malicious behavior.

· This new feature is referred to by our developers as Neural Network technology — a method that uses advanced statistical analysis to automatically determine if an unknown program is malicious. It’s a cool new technology that provides better detection and reduces the occurrence of false positives to ensure a superior user experience.

· ThreatFire’s advanced malware cleanup ability is now even better. ThreatFire 4.7 contains tracker technology to more accurately trace the original source of the threat and ensure that only the malicious program is quarantined and legitimate programs are unaffected. This enables ThreatFire to do a more thorough clean up, provides confidence that your system will not be compromised or destabilized, and ensures ThreatFire safely identifies all of the components of a malicious program.

· As always — ThreatFire continually searches for active rootkits on your system in real time — but some of the more complex rootkits require deeper scanning in order to be detected. As a result, ThreatFire 4.7 has added new rules for detecting both known and unknown threat outbreaks to provide better protection.

· This new version of ThreatFire also employs unique technologies in an enhanced rootkit scanner to help protect you from deeply hidden threats. PC Tools recommend setting up regular rootkit scans as a precaution against these particularly nefarious types of threats (this can be done in the ThreatFire settings menu).

· PC Tools recognizes that traditional signature-based anti-virus scanners have become a less effective, secondary line of defense to proactive behavioral based protection. User feedback has also indicated that ThreatFire is useful as the first line of protection in addition to traditional signature-based virus scanners. As a result, ThreatFire 4.7 focuses on delivering best-of-breed behavioral protection and no longer provides a traditional signature-based virus scanner.1

· The Smart Update feature now includes several options to give you greater control over how and when updates are applied. The new update options include "download and install automatically", or "notify before installing updates".

· ThreatFire is now only available as free version; Pro version no longer available2
· Now supports Vista 64-bit and Windows 7 (32-bit and 64-bit)
· More intuitive alerts with enhanced technical details and additional new option to “Kill the process”
· New PC Tools News and Blog view added to easily read updates on latest threats and other announcements
· New PC Security Check runs during install to check PC security status
· Support for Windows 2000 has been discontinued in ThreatFire v. 4.5.3
