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.

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.

avast! 4 Home Edition is a full-featured antivirus package designed exclusively for home users and non-commercial use. Both of these conditions should be met! ALWIL Software offers the Home Edition free of charge, since, in our opinion, it is possible to avoid global virus spreading by efficient prevention; however, many users are not able to or do not want to pay for antivirus software.

avast! 4 Home Edition features:
The latest version of avast! antivirus kernel features outstanding detection abilities, together with high performance. You can expect 100% detection of In-the-Wild viruses (viruses already spreading between users) and excellent detection of Trojan horses.

The Simple User Interface is used to start on-demand scanning, work with the results and change various options. Basic resident protection settings can be modified here. The Simple User Interface is the main application of avast! 4 Home Edition. You can start additional avast! modules from here, such as the Virus Chest, Updater or Log Viewer.

Resident protection (the real-time protection of the operating system), is one of the most important parts of an antivirus program today. avast! features a powerful resident module that is able to detect a virus before it has any chance to infect your computer.

Avast features a module for the protection of IM (Instant Messaging, “chat”) programs, and a module for the protection of P2P (peer-to-peer) programs. The list of supported IM and P2P programs is extensive with more than 30 programs currently supported.

A new resident protection module was added to avast! 4.5: the Network Shield. This module provides protection against known Internet worms/attacks. It analyses all network traffic and scans it for malicious contents. It can be viewed as a lightweight firewall (or more precisely, an IDS (Intrusion Detection System)).
