Server Edition Plug-ins
avast! 4 Server Edition is the most powerful protection to fight virus infection of your Windows-based server or servers (for protection of Linux-based servers, please refer to avast! for Linux). It works both as a classic protection of file-servers and, via its optional plug-ins, as a protection of various subsystems running on the server, including electronic mail, firewall/proxy etc.
Currently, the following plugins (editions) are available:
avast! 4 Exchange Server Edition - antivirus for Mail & SMTP Servers 
Protection for Microsoft Exchange 2000, 2003 and 2007 Servers. Features high-performance scanning, superior scalability and support for clustering (even in Active-Active mode). Perfectly integrates with Exchange via Microsoft's own Virus Scanning APIs.
Antivirus solution for your MS ISA 2000 Servers or higher (also works with MS Proxy Server 2.0). Provides real-time scanning of HTTP and FTP traffic at the gateway, greatly reducing the risk of infection from the World Wide Web (including web-based mails etc.).
avast! 4 SharePoint Server Edition 
This plugin offers real-time scanning on the following Microsoft SharePoint server versions: MS SharePoint Portal Server 2001, MS SharePoint Portal Server 2003, Windows SharePoint Services 2003 and MS Office Sharepoint Server 2007.
The SMTP Server Edition works as a plug-in to the Microsoft SMTP Service (part of the IIS). It can be deployed on a machine that acts as a universal gateway (or border server) for scanning purposes only - no matter which mail server you actually use.
antivirus avast! 4 Lotus Domino Edition 
avast! Lotus Domino Edition works as a plug-in to Lotus Domino Servers (Windows platform only). It provides on-access scanning of Domino mail traffic as well as on-demand scanning of Lotus Notes/Domino databases (.NSF files).
