Sophie is a daemon which uses 'libsavi' library from Sophos anti-virus vendor (http://www.sophos.com). On startup, Sophie initializes SAPI (Sophos Anti-Virus Interface), loads virus patterns into memory, opens local UNIX domain socket, and waits for someone to connect and instructs it which path to scan. Since the database is loaded in RAM, scanning is very fast. (Note: speed of scanning also depends on SAVI settings and size of the file.) It works on Linux, Solaris (Sparc/x86), HP-UX, and FreeBSD.
DansGuardian Anti-Virus Scanner
The DansGuardian Anti-Virus Scanner gives you the ability to virus-scan all content that passes through DansGuardian. It uses the scanning code from the MailScanner project to do the actual virus scanning, so it supports all the virus engines that the MailScanner project supports. The scanning is done as the file is being downloaded, so your current network apps don't have to be modified, etc. They just have to support using a proxy.
amavis-notify-parser analyzes hostmaster notifications from Amavis and writes a logfile which records the type and origin of the viruses detected. It requires only a piped mail alias, a PHP4 CGI binary, and Amavis. McAfee uvscan is supported as the virus scanner. The logfile may be output in qmail's logfile format.
ScannerDaemon is the virus scanner of the OpenAntivirus project. You can send a filename to it via simple TCP and it will scan the file for virii and tell you if the file is infected or not. The ScannerDaemon comes with its own virus database, so you do not need any commercial virus scanner. There is a plugin for AMaViS to scan all EMail going through a mail server.
exiscan is a patch against exim version 4, providing support for content scanning in email messages received by exim. It works after the sending client has completed the SMTP data phase and waits for an answer from the server. Messages containing unwanted content can be rejected at that stage, so the job of generating a bounce message is the job of the sending host. Four different scanning facilities are supported: antivirus, antispam, regular expressions, and file extensions.
samba-vscan provides on-access scanning of Samba shares for Sophos Sweep+Sophie and Trend Micro+Trophie. It supports Samba 2.2.x with working virtual file system (VFS) support.
Mailscanner for Postfix
This program is invoked from the .forward file of a user and scans the incoming mails for .vbs .exe .com .bat, and similar attachments. If a message is clean, it is inserted into the users qmail-style Maildir. Otherwise, it is bounced.
Trophie is a daemon which uses libvsapi library from TrendMicro, an antivirus vendor. On startup, Trophie initializes VSAPI, loads virus patterns into memory, opens a local Unix domain socket, waits for someone to connect, and instructs it which path to scan. Since the database is loaded in RAM, scanning is very fast.
Milter-Virus is a wrapper which allows you to use virus scanners like F-Prot in sendmail. It filter incoming and outgoing mail. The configuration file allows chaining of scanners and blocking of certain bad double file extensions
Mikrop is a small, easy to install program for mail servers to scan incoming email. It uses third party virus scanners, and is currently integrated with the Postfix MTA.
