A ôZero-Dayö attack occurs when your computer is infected by a Zero-Day threat û a virus, trojan, worm or spyware which is so new that traditional antivirus programs have no ôsignatureö to identify the threat.
Because Zero-Day attacks happen faster than traditional antivirus vendors can react.
Here is what your traditional signature-based antivirus product must do to protect you against any new threat:
1) Catch the threat.
2) Analyze the threat to understand what it does
3) Write a signature that recognizes the threat.
4) Test the signature to ensure it does not damage your computer.
5) Issue you an update with the new signature. And thenà
6) You still have to update your software with the new signature!
It can be days before traditional antivirus vendors provide the ôsignature updateö necessary to protect your computer. And traditional signatures cannot protect you if a threat ômorphsö to evade the signature.
ThreatFire does not rely on signatures in order to protect you. Its patent-pending ActiveDefense technology is the most intelligent behavioral analysis technology available today. It continuously monitors all activities on your PC at a very low system level and uses a proprietary combination of analytics, risk algorithms, program histories and tolerance thresholds to identify and shut down threats.
When ThreatFire detects an attack on your computer by a known virus, it will immediately terminate the attack and permanently isolate the virus process. An alert screen will appear to confirm that ThreatFire has prevented the attack.
If ThreatFire detects a potentially malicious process that might be an attack, it will immediately suspend the suspicious process and alert you that your computer is at risk. You can then choose to ôAllowö or ôQuarantineö the process based on the informative information provided in the alert.
