Spyware is software installed on a computer that is designed to collect
information about the computer user, often without their knowledge or
consent. This can result in so called identity theft, or theft of
valuable information (e.g. bank or credit card details) or proprietary
business data. Spyware is often developed by organized crime rings
rather than lone individuals and may be installed by a virus.
Certified by West Coast Lab’s Checkmark process, avast! has full
anti-spyware capabilities built-in, to make your protection even more
Rootkits are programs that install on your computer while keeping
themselves and their activities hidden to remain invisible to the use.
They represent a significant security risk on both home computers and
company networks and are notoriously difficult to find and remove.
Rootkits themselves are normally installed by a virus or other type of
malware infection and it is therefore highly recommended that computer
users have up to date antivirus/anti-spyware software installed and
running on their computer. One such system is avast! antivirus.
Based on the class-leading GMER technology, avast! can now scan your
live system for rootkit infections; no boots disks are required. If a
rootkit is discovered, it is initially disabled and then if it can be
safely removed without affecting the performance of the computer, it is
removed. avast! antivirus includes a virus database which can be
automatically updated to provide continuous protection against
Some viruses may attempt to switch off a computer’s antivirus software.
To help keep your protection working, even against the latest threats
that may try to disable your security protection, avast! has
best-in-class strong self-protection built in, to make sure, no matter
what you face, avast! carries on protecting your valuable data and
programs. This is based on the multi-award winning avast! antivirus
technology and provides an extra layer of security to ensure your data
and programs are always protected.
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 kernel is certified by ICSA Labs; it 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.
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.
The appearance of the Simple User Interface is very flexible. It
supports so-called skins (changeable appearance of the application), so
you can change the interface to suit you. The main package contains
three skins, with additional skins available from our web pages.
Enhanced User Interface
In addition to the Simple User Interface, the Professional Edition
presents the Enhanced User Interface, giving you access to all features
and possibilities for extensive scanning control.
Unlike the Simple User Interface, the scanning is performed by
so-called “tasks”. First, you define a task, including various
parameters – areas to scan, what to scan, how to scan, etc. Having the
task, you can run it (possibly repeatedly). Each task generates a list
of results, which you can work with later.
Another key feature, closely connected with tasks, is the Scheduler.
This feature gives you the ability to schedule the tasks running,
either one-time or periodically.
Additionally, it is possible to set all existing scanning options, a feature not available in the Simple User Interface.
Resident protection (the real-time protection of the computer system),
is one of the most important features 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! Professional Edition contains resident protection of the
computer file system and a resident module for e-mails and news.
File system protection ensures that no virus will be started on the
computer. It offers a wide range of settings, such as the possibility
to specify that files will be scanned during copying, or scanning will
include files with a given set of extensions only.
E-mail/News protection consists of two independent modules; first,
there is a generic scanner working on the SMTP/POP3/IMAP4/NNTP protocol
level. It is capable of protecting any existing e-mail client that uses
these protocols. Second, there is a special plugin for MS Outlook only;
with mail scanning completely transparent, requiring no special
A new feature of version 4 is heuristic analysis of e-mail scanners.
This feature can protect against new, unknown viruses and worms that
are not possible to detect by the usual means. The heuristic module
performs a thorough investigation of every e-mail message and watches
for suspicious signs that might announce virus presence. When the
number of those signs exceeds the user-defined level, the message is
considered dangerous and the user is warned.
The resident protection of the Professional Edition includes an
additional module, not contained in the Home Edition, called Script
Blocker. This module watches all scripts being executed in the
operating system (so-called WSH scripts – Windows Scripting Host), and
scans all the scripts run as a part of a web page within your web
browser (Internet Explorer, Netscape Navigator and Mozilla).
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.
While chat itself would not pose any serious security risks in terms
of viruses, today’s IM applications are far from being just chatting
tools: most support more or less sophisticated file sharing methods –
which may quite easily lead to virus infections, if not properly
The P2P protection module doesn’t need much explanation – today’s
P2P networks (such as Kazaa) contain potentially thousands of infected
files, and effective protection is essential.
Web Shield is a unique feature of avast! that enables it to monitor and
filter all HTTP traffic coming from 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 effective countermeasures has also increased. Web Shield acts
as a transparent HTTP proxy and is compatible with all major web
browsers, including Microsoft Internet Explorer, FireFox, Mozilla and
Unlike most competitive solutions, Web Shield’s impact on browsing
speed is almost negligible. This is because of a unique feature called
“Intelligent Stream Scan” that lets the Web Shield module scan objects
on-the-fly, without the need of caching. Stream scanning is performed
in operating memory only (without the necessity to flush the contents
to disk), providing maximum possible throughput.
Automatic updates are another key 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
updates are tens of KB; program updates typically are in the hundreds
of KB range.
If your Internet connection is persistent (such as an always-on
broadband connection), then updates are performed completely
automatically at fixed time intervals. If you connect to the Internet
only occasionally, avast! watches your connection and tries to perform
the update when you are online.
A special feature of the Professional Edition is PUSH updates. It is a
dramatic change in the philosophy of updates. Usually, every installed
program checks occasionally for new version availability. PUSH updates,
however, are initialized by our server; they result in your computer
quickly responding and performing the necessary update. The system is
based on the SMTP protocol (as used for e-mail messages). The update
itself is controlled by the avast! resident e-mail providers (MS
Outlook and Internet Mail).
The whole system is protected by asymmetric ciphers and is resistant to unauthorized misuse.
The Virus Chest can be thought of as a folder on your disk drive,
having special properties that make it a safe, isolated place suitable
for storing certain files. You can work with the files in the Chest,
though with some security restrictions.
The main properties of the Virus Chest are complete isolation from
the rest of the operating system. No outside process, such as a virus,
may access the files inside, and the fact that the files inside the
Chest may not be run (executable), there is no danger in storing
avast! antivirus features outstanding integration into your system. A
scan can be started directly from Windows Explorer, by clicking a
folder or a file with your right mouse button and selecting the
corresponding choice from the menu.
A special screen-saver is also provided, that, when running,
performs virus scanning. avast! antivirus works together with your
favorite screen-saver, so you don’t have to change your personal
settings to use it.
A new option in this release is the boot-time scan (Windows
NT/2000/XP/Vista 32bit only). This important feature allows a user to
instigate scanning before a virus is activated, in the case that a
virus is suspected to be active on your computer already.
For experienced users, the Professional Edition features a command-line
scanner. Scanning can be controlled by many arguments and switches; to
use as a pipe filter; and a special STDIN/STDOUT mode is available.
The module is intended to be used in BATCH programs. Its output is
the same as the output from the Enhanced User Interface tasks
(including the report files).
Integrated avast! Virus Cleaner
Since version 4.1, avast! includes Virus Cleaner, a tool designed for
the complete removal of most common infections from already-infected
computers. So now avast! is capable of reliably healing, and not just
detecting, the most common malware.
The number of viruses/worms supported by the Virus Cleaner is
constantly growing. For the most up-to-date information we suggest
visiting Virus Cleaner’s own page. Note: For emergency purposes, we
also offer Virus Cleaner as a standalone product, capable of running
without installing avast!.
Support for 64-bit Windows
avast! Home/Professional now fully supports the 64-bit Windows
platform. ALWIL Software is anticipating massive growth 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. This reduces the time for loading data
into virtual memory or seeking, reading, and writing to data storage
devices, making applications run faster and more efficiently.
Regular (32-bit) antivirus applications are unable to operate
correctly on the 64-bit Windows platform, because they rely on 32-bit
kernel-mode drivers. The latest version of avast! uses native 64-bit
drivers, delivering the same level of protection as the 32-bit Windows
environments. The installation package is the same for 32-bit and
64-bit versions – the setup program automatically detects the operating
system it is running on and installs all necessary files. You may find
more information on avast! Antivirus and Windows x64 Edition page.
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, currently the list of supported languages is: English,
Arabic, Bulgarian, Catalan, Chinese (both Simplified and Traditional),
Czech, Danish, Dutch, Finnish, French, German, Greek, Hungarian,
Italian, Japanese, Korean, Malay, Norwegian, Polish, Portuguese (both
Brazilian and Portugal), Romanian, Russian, Serbian, Slovak, Slovenian,
Spanish, Swedish, Turkish.
A new resident protection module was added to avast! 4.5: the Network
Shield. This module provides protection against known Internet
worms/attacks. It analyzes all network traffic and scans for malicious
content. It can be viewed as a lightweight firewall (or, more
precisely, an IDS (Intrusion Detection System)).
The Network Shield is only available on NT-based systems (Windows NT/2000/XP/Vista).
