avast! 4 Server Edition is the most powerful protection available to fi ght virus infections on your server or servers. It works for both
standard protection of a file server, and also via its optional plug-
ins, as protection of various subsystems running on the server, e.g.
electronic mail, fi rewall/proxy etc. Currently, the following plugins (editions) are available:
- MS Exchange Server 2000/2003
- MS Proxy/ISA Server
- SMTP Server
- MS Sharepoint Server (Portal Server 2001/2003 and Windows
- Sharepoint Services 2003)\
Antivirus Kernel
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 and Trojan horses.
The kernel is certifi ed by ICSA; it frequently takes part in the tests of Virus Bulletin magazine, often yielding
the prestigious VB100 award.
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! in a terminal environment, you can use another wizard
that guides you through the reconfi guration of the avast! system to
work in the terminal mode. Such a reconfi gured 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 a 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 fl awlessly.
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 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.
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 use.
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 to offer complete isolation from the rest of the operating system. |
The file system protection ensures that no virus will be executed on
startup, and no virus will even be uploaded. The default settings of the resident protection are accommodated to the server environment
which it provides thorough scanning. It is possible to adjust the
settings to your equirements so you can specify to scan the copied
files, or just files with a given set of extensions, etc. An important new feature is the “semi-silent“ mode of operation. The purpose is to correctly display virus warnings on a server system. It
works as follows: 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 ran parallel).
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 confi gure it for extensive scanning.
The main principle is called “antivirus task“ based scanning. First,
you defi ne the tasks used to scan for viruses, including the common
parameters. Then, you run these tasks (usually periodically). Every task
generates some results which you can work with 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-off and
periodically.
Notifi cation Manager
To make work easier, Server Edition contains a special notifi cation
manager. Here, you can defi ne notifi cation objects and associate
them with antivirus tasks (both “resident“ and “on-demand“). Those
notifi cation objects are then used in the case when a virus is found.
The new version supports a number of notifi cation objects, such as
sending e-mail messages using SMTP or MAPI (Outlook). Also supported
are; SMS, notifi cation using the Windows popup mechanism (network
message), printing the message on a network printer, SNMP traps, and
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 fi xed time intervals. If you connect to the
Internet only occasionally, avast! watches your connection and tries to
perform the update when you are online
Boot-time Scan
A special avast! feature is the boot-time scan. It is important in the case that you 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, in addition 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) |
