avast! 4 Server Edition offers the most powerful protection to fight virus infections on your server or servers. It works both as primary protection of a file server itself, and, via its optional plug-ins, as protection for various server subsystems, such as electronic mail or firewall/proxy. 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)
