Currently, the following plugins (editions) are available:
- MS Exchange Server 2000/2003
- MS Proxy/ISA Server
- SMTP Server
- MS Sharepoint Server (both Portal Server 2001/2003 and Windows Sharepoint Services 2003)

Antivirus Kernel
The latest version of avast!
antivirus kernel features world-class detection abilities together with
high performance (data throughput). You can expect 100%
detection of In-the-Wild viruses and Trojan horses.
The kernel is certified by ICSA and the product frequently takes part in the tests of Virus Bulletin magazine, yielding multiple VB100% awards.
Direct Cluster
and Terminal Services support
avast! 4 Server Edition
is ready to work and even supports large
cluster and terminal servers. It contains direct support
for cluster setup, including a special wizard that
makes the installation on cluster easier.
To set up avast! on terminal environment, you can use another wizard that guides you through the reconfiguration of avast! system for the work in terminal mode. Such a reconfigured avast! system looks (and behaves) to the terminal users as the standard avast! would for workstations.
The support for the terminals is not limited to the terminal services by Microsoft; it is fully functional with Citrix MetaFrame system as well.
Integration with the Operating
System
avast! 4 Server Edition has been fully
tested with all editions of Windows Servers (starting
with NT 4.0 and up to Windows Server
2003, including Windows Storage Server 2003 and Windows
Datacenter Server 2003). It is fully optimized to
take advantage of multiple CPUs and has been
stress-tested even on machines with a large number
of processors to verify exceptional robustness and scalability
of its technology.
Special care has been taken to ensure 100% compatibility with advanced server components such as the VSS (volume shadow copy) and FRS (file replication services), guaranteeing that your server will run flawlessly under all circumstances.
64-bit support
avast! 4 Server Edition works perfectly even on
IA-64 and AMD-64 based machines. It is one
of the very few AV solutions on the
market that covers this fast-emerging platform that is
likely to gain more and more importance in
the upcoming years.
Resident Protection
Resident protection which
is the real-time protection on 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.
The file system protection ensures that no virus will be executed on startup, and no virus will be even uploaded to it. The default settings of the resident protection are accommodated to the server environment - it provides thorough scanning. It is possible to adjust the settings to your requirements; you can specify to scan the copied files, or just files with given set of extensions, etc.
An important new feature is so-called "semi-silent" mode of operation. The purpose is to correctly display virus warnings on a server system. It works like this: if a request to load an infected file comes from a network, an automatic action is taken and nothing is displayed. On the other hand, when the request comes from a local or terminal session, the usual interactive mode is used - as in desktop antivirus.
The resident module is highly optimized for speed and tested even in heavy load. It fully utilizes the possibilities of today's powerful servers, such as multiple CPUs (the scanning can be parallelized).
Developed especially to use on Terminal Server, avast! 4 Server Edition contains additional resident modules for e-mail protection (Outlook/Exchange, Internet Mail) and browser protection (Script Blocker).
User Interface
Even though the Server Edition contains both the
user environments of avast! - simple and enhanced
- in server usage usually the enhanced user
interface will be employed (except for the terminal
server). The enhanced user interface gives you access
to all the settings of avast!, thus making
it possible to fully configure it for extensive
scanning.
The main principle is so called "antivirus task" based scanning. First, you define the tasks used to scan for viruses, including the common parameters. Then, you run these tasks (probably periodically). Every task generates some results; of course, you can work with these results afterwards. Resident protection is also a special type of task.
Another feature, closely connected with tasks, is the Scheduler. It makes it possible to schedule the start of a particular task, both one-time and periodically.
Notification Manager
To make work easier, Server Edition
contains a special notification manager. Here, you can
define notification objects and associate them with antivirus
tasks (both resident and on-demand). Those notification objects
are used in the case when a virus
is found.
The new version supports a number of notification objects, such as sending e-mail messages using SMTP or MAPI (Outlook) Also supported are; SMS as well, notification using the Windows popup mechanism (network message), printing the message on a network printer, SNMP traps, or even sending IM messages using MSN/Windows Messenger.
Automatic Updates
Automatic updates
are another key point in virus protection, both
the virus database and the program itself can
be updated automatically. The updates are incremental, and
only new data is downloaded, thus reducing the
transfer time. The typical size of a virus
database update is approximately of 20-80kb, the program
update usually has approximately 200-500kb.
If your Internet connection is persistent, the updates are performed completely automatically in 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.
Push Updates
A special feature
of the Server Edition is PUSH updates. It
is a dramatic change in the philosophy of
updates, usually every installed program checks periodically and
when a new version is available downloads it.
PUSH updates however are initialized by our servers;
they result in your computer quickly responding and
performing the necessary update. The system is based
on the SMTP protocol. The updates themselves are
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.
Virus Chest
The Chest can be
thought of as a Quarantine area on your
disk having special properties that make it a
safe isolated place suitable for storing certain files.
You can work with the files in the
Chest with security restrictions.
The main properties of the Virus Chest are complete isolation from the rest of the operating system.
Boot-time scan
A
special avast! feature is the boot-time scan. It
is important in the case of suspect that
there might be an active virus on the
computer. The boot-time scan is performed during the
start of the operating system, before the virus
can get loaded/activated - thus preventing the virus
from spreading or taking actions to avoid being
detected.
Command-line Scanner
Experienced users may like another
Server Edition feature which is the command-line scanner.
The scanning can be controlled by many arguments
and switches; it can be used as a
pipe filter, also 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).
