ThreatFire™ AntiVirus protects when others can't

PCs are under constant attack from viruses, spyware and identity theft. Every day you hear about a new threat to your PC. They're coming faster than ever before, they're getting harder to stop and traditional antivirus products are not able to keep up.

Will your antivirus software catch the latest malware that just came out today? In most cases, no, because it simply does not know how to detect it yet. But ThreatFire's ActiveDefense technology does, and has proven to provide up to 243% more protection when combined with traditional AntiVirus products. See the table below.

If I already have antivirus software why do I need ThreatFire?

ThreatFire is dramatically different to traditional antivirus software. Normal antivirus products usually need to have first identified and seen a threat before they can provide adequate protection against it. The protection is then provided via a signature or fingerprint update, which must first be written by an antivirus researcher. This creates a large window of time where threats are undetected and can therefore infect your PC even when you have antivirus software installed.

How can ThreatFire protect me when traditional antivirus can't?

ThreatFire continually protects your PC against attacks by detecting malicious behavior, such as capturing your keystrokes or stealing your data, instead of only looking for known threats like normal antivirus software. By implementing sophisticated real-time behavioral analysis ThreatFire is able to stop never- before-seen "zero-day" threats solely by detecting their malicious activity.

Zero-day threats are usually designed to take advantage of new vulnerabilities or exploits that are currently unprotected by traditional security products. They are usually distributed in huge quantities very quickly by mass email (SPAM), website hijacks, instant messaging or over peer-to-peer networks. Because they are undetectable they are able to wreak havoc and compromise your PC even when you have up-to-date antivirus software installed.

ThreatFire's patent-pending ActiveDefense technology offers protection against all types of internet threats - both known and unknown - spyware, adware, keyloggers, viruses, worms, Trojans, rootkits, buffer overflows, and other malware. ThreatFire uses its unparalleled protection to hunt down and paralyze those threats that are either too new or too clever to be recognized by traditional "signature-based" antivirus software.

Do I need to be an expert to use ThreatFire?

ThreatFire is advanced technology designed especially for people, not just experts.

We believe security software should be "set and forget" so once you install ThreatFire you won't need to answer lots of technical questions, in fact the only time you should even notice ThreatFire is protecting your PC is when we detect something malicious that requires your attention.
