Spybot - Search & Destroy detects and removes spyware, a relatively new kind of threat not yet covered by common anti-virus applications. Spyware silently tracks your surfing behavior to create a marketing profile for you that is transmitted without your knowledge to the compilers and sold to advertising companies. If you see new toolbars in your Internet Explorer that you haven't intentionally installed, if your browser crashes inexplicably, or if your home page has been "hijacked" (or changed without your knowledge), your computer is most probably infected with spyware. Even if you don't see the symptoms, your computer may be infected, because more and more spyware is emerging.

ThreatFire is an easy-to-use 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.

New features:

- Cyberhawk is now named ThreatFire, which has a new look and feel and is branded as a PC Tools product. The basic product layout and functions are similar to the older version, so hopefully it will be easy to make the switch to ThreatFire.
- Certain features previously found only in Cyberhawk Pro are now available in the new free product: ThreatFire Free Edition. These features include malware quarantine and removal, advanced custom rules, the rootkit scanner, and the built-in search on ThreatFire alerts which allows you to find out additional information on a threat.
- The “potentially malicious”alerts (yellow alerts) now give the option to Allow or Quarantine,instead of Allow or Deny. This is because ThreatFire is now able toquarantine any threats it detects, not just threats that wereclassified as “known” malware.
- The new Pro version includes theon-demand scanning piece of PC Tools AntiVirus so that you can scanyour system for dormant threats that may not be caught by ThreatFire’sreal-time behavior-based protection. This AV scanner greatly increasesthe overall protection offered by ThreatFire and offers protection froma full spectrum of both known and unknown threats.
- Greatly improved the overall protective capability of ThreatFire since the Cyberhawk v. 2.04 release.
- Fewer false positives.
- Miscellaneous other program fixes. 

Notes: 

ThreatFireis the new name of the behavior-based anti-malware program formerlyknown as Cyberhawk. With this release of v. 3.0 and going forward, theprogram will be known as ThreatFire and support for Cyberhawk will beshifted to ThreatFire.
