The key functions and benefits of avast! Home Edition include: Antivirus kernel: The latest version of avast! antivirus kernel features outstanding detection abilities, together with high performance. We can expect 100% detection of In-the-Wild viruses (viruses already spreading between users) and excellent detection of Trojan horses. The kernel is certified by ICSA; and frequently takes part in the tests of Virus Bulletin magazine, often yielding the VB100 award. The avast! engine also features outstanding unpacking support. It can scan inside the following archives: ARJ, ZIP, MIME (+ all associated formats), MAPI (Outlook pst files), DBX (Outlook Express archives), RAR, TAR, GZIP, CAB, BZIP2, ZOO, ACE, ARC, LHA/LHX, TNEF (winmail.dat), CPIO, CHM, RPM, ISO, 7ZIP and SIS. It also supports a number of executable packers (such as PKLite, Diet, UPX, ASPack, PeShield, FSG, MEW etc.). Last, but not least, it can also scan for viruses hidden in Alternate data streams on NTFS volumes.

Simple User Interface: 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.

Standard resident protection: 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 our computer. avast! Home Edition contains resident protection of the computer file system and a resident module for e-mails and news.

P2P and IM Shields: 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.

Network Shield: 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)).

Web Shield: Web Shield is a unique feature of avast! that enables it to monitor and filter all HTTP traffic coming from the Web sites on the Internet. Since an increasing number of viruses (and other malware, such as adware, spyware and dialers) are being distributed via the World Wide Web, the need for an effective countermeasures has also increased.

Automatic updates: Automatic updates are another need in virus protection. Both the virus database and the program itself can be updated automatically. The updates are incremental, with only new or missing data downloaded: thus reducing the transfer heavily. The typical size of a virus database update are tens of KB; program updates are typically in the hundreds of KB range.

Virus Chest: The Virus Chest can be thought of as a folder on our disk drive, having special properties that make it a safe, isolated place suitable for storing certain files. We can work with the files in the Chest, though with some security restrictions.

System Integration: avast! antivirus features outstanding integration into our system. A scan can be started directly from Windows Explorer, by clicking a folder or a file with our right mouse button and selecting the corresponding choice from the menu. Integrated avast!

Virus Cleaner: Since version 4.1, avast! includes the Virus Cleaner, a tool designed for a complete removal of most common infections from already-infected computers. So now is avast! capable even to reliably heal (not only detect) the most common malware.

Support for 64-bit Windows: avast! Home/Professional now fully supports the 64-bit Windows platform. ALWIL Software is anticipating massive take-up of this platform, as Windows XP 64-Bit Edition will support up to 32 GB of RAM and 16 TB of virtual memory, enabling applications to run faster when working with large data sets. Applications can preload substantially more data into virtual memory, allowing rapid access by the 64-bit extensions of the processor.

Internationalization: Commitment to internationalization is one of the key benefits of avast!. During the last 2 years, avast! has been translated to a number of languages and the latest version added additional language modules.
