*** Antivirus Kernel
New version of
avast! antivirus kernel features outstanding detection abilities,
together with high performance. You can expect 100% detection of
In-the-Wild viruses (the ones what are really spreading amongst people)
and very good detection of Trojan horses, all that with only a minimum
number of false alarms.

The kernel was certified by ICSA; it frequently takes part in the tests
of Virus Bulletin magazine, often yielding the VB100 award.

*** Simple User Interface

Simple User Interface is used to start on-demand scanning, work with
the results, change various options etc. Basic resident protection
settings can be modified here. 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.

*** Enhanced User Interface

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 (possibly repeatedly) run it. Each task generates a list of
results; you can work with them later.

*** Resident protection

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

E-mail protection consists of two independent modules; first, there is
a generic scanner working on the SMTP/POP3/IMAP4 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; it is
completely transparent, requiring no special settings.

New feature of version 4 is heuristic analysis of e-mail scanners. It
is extremely useful in protecting 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.

*** Script Blocker

The resident protection of the Professional Edition includes an
additional module, not contained in the Home Edition - Script Blocker.
This module watches all the scripts being executed in the operating
system (so called WSH scripts - Windows Scripting Host). It also scans
all the scripts run as a part of a web page within your web browser
(Internet Explorer, Netscape Navigator and Mozilla).

*** Automatic updates

Automatic updates are another key point in virus protection. Both the
virus database and the program itself can be updated automatically.

*** PUSH updates

A special feature of the Professional Edition are PUSH updates. It is a
dramatic change in the philosophy of updates. Usually, every installed
program checks every now and then whether a new version is available.
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, i.e. on usual e-mail
messages. The updates itself are controlled by the avast! resident
e-mail providers (MS Outlook and Internet Mail).

*** Virus Chest

The main properties of the Virus Chest are complete isolation from the
rest of the operating system (no outside process, i.e. no virus either,
may access the files inside) and the fact that the files inside the
Chest may not be run (i.e. there is no danger in storing viruses
there).

*** System integration

avast! antivirus features outstanding integration into your system. The
scanning 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.

Another interesting feature is a special screen-saver that performs
scanning for viruses during its run-time. avast! antivirus works
together with your favorite screen-saver, so you don't have to change
to anything you wouldn't like.

Another new option is the boot-time scan (Windows NT/2000/XP/.NET
only). It is important in the case that a virus is suspected to be
active on your computer. The boot-time scan is performed before the
virus may get activated, so the virus cannot influence the scanning in
any way.

*** Command-line scanner

Experienced users may like another Professional Edition feature -
command-line scanner. The scanning can be controlled by many arguments
and switches; to use as a pipe filter, 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).
