AntiVirus Scanner is an anti-virus scanner for Endeavour Mark II that uses the ClamAV library (libclamav).

AntiVirus Scanner allows you to create a list of scan items for frequently scanned locations and features easy virus database updating, all in a simple GUI environment.

protector scans e-mail attachments in order to identify those that could (by nature of their type) contain viruses or other undesirable content, and replaces them with a warning message. Protector is designed to be used on a unix mail gateway server MS Windows clients by way of a POP3 service. Typically, protector blocks DOS or Windows executables, DLLS etc Files with double extensions like "picture.gif.exe" Visual basic (VB) scripts Word documents that contain macros unrecognised file types ... etc ...

Protector is NOT a virus scanner in the traditional sense: It does NOT scan attachments for virus signatures, but blocks or edits attachments that could contain viruses. So *.exe, *.vba etc attachments dont get through. This means that you dont have to keep protector up to date to stay protected against the growing tide of new viruses and worms.

Protector does not work by blocking listed types, but by blocking a set of listed types.

The logic employed by protector to determine the file types contained in attachments is based on a modified version of the "file" command, and a number of type-specific validation programs - it does not rely on the actual name of the file, or the "content-type" declared in the attachment header. It also looks inside ZIP, TAR and other archive formats, and checks the files contained in them.

Some types of files are allowed through only under certain conditions. The main example being that MS Word documents are blocked if they contain ANY macros, but allowed through otherwise.

Protector grew out of a need to protect a small network that I manage in my spare time from the dangers of e-mail borne viruses and trojans. A number of installations exist round the world and feed back from users has allowed me to improve the system - in terms of reliability, performance, ease of use and the breadth of file types "allowed through". Development is still underway, and a new release will be available shortly that allows a far larger set of file types through, allows scripts to be removed from attachments (eg: JavaScript can be removed from HTML files), and is significantly easier to tailor.

Constructive critisism is warmly invited

gadoyanvirus is a virus checker for qmail that works with the QMAILQUEUE patch by Bruce Guenter. gadoyanvirus scans incoming messages using the ClamAV anti-virus library.

Suspected messages are quarantined and a notification message can optionally be sent to the recipients.

Viralator is a Perl script that virus scans HTTP/FTP downloads request on a UNIX server after passing through the Squid proxy server.
Even when I implemented virus protection for my network email server we still continued to get the odd virus. Most of the viruses came from people using free webmail accounts like Hotmail or Yahoo and downloading the infected attachments to their machines or through downloading junk.
Rather than block access to the users I decided to look at how we could better protect the network. I looked at a couple of different products both comercial and free but they were either too expensive or did not meet my needs.
That is how Viralator was born. Viralator Proxy Virus Scanner is licenced under the GPL.
Viralator should work in any UNIX system that uses Apache and Squid servers. We have reports about successful instalations on:
- RedHat Linux
- Mandrake Linux
- SuSe Linux
- e-Smith Linux
- Slackware Linux
- Conectiva Linux
- Debian Gnu Linux
Supported Redirectors:
- Squirm
- SquidGuard
- Jesred
Supported Virus Scanners
- AntiVir
- AVP
- RAV
- Inoculate
- Sophos Sweep
- McAfee
- Trend
- Clamav
- Bit Defender (free edition)
The original concept for Viralator came from the Viromat project. Without Viromat the Viralator project would not have had a starting point. We can also thank Ralph Meyer for badgering me into releasing the script under the GPL.
Enhancements:
- Parenthesis are included on the regular expression used to validate URLs.
- The character set checking step, which was not working before last patch released, has been fixed.

Milter-virus is not a virus scanner. It is a wrapper that can be used with many commercial and freely available virus scanners. Milter-Virust is written completely in C, and requires (few skills??).
It is run-able with the Milter interface, but then will only scan for "double extensions".
If you wish it to scan for more, you need at Ripmime or other tools to extract files from MIME-encoded emails. You also need a (command-line) virus scanner.
The difference between this program and the original is that this is much more configurable via the config file. The original version has the advantage that it is simpler and easier to bugfix.
Enhancements:
- This is a large update.
- Many problems in the statistik module were fixed.
- Some spam protection features were included.

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 viruses and tell you if the file is infected or not.
The ScannerDaemon listens on localhosts port 8127 for absolute filenames and absolute directorynames. It scans the files/all files in the directory and reports OK if no virus has been found or FOUND: if a virus has been detected.
You can start the ScannerDaemon simply by typing:
java -jar ScannerDaemon.jar
If you did not forget the Credo-files, it should come up and listen on port 8127. You can also give the name of the directory as a command-line parameter, like
java -jar ScannerDaemon.jar -credo.directory
Enhancements:
- Adaptions to new listener and filter scheme
- Bugfix: allow more than one signature file in one credo file
- Bugfix: close files used by UPXFilter
- Bugfix: wrong failure transitions
- Improvement: less memory consumption for nodes
- Improvement: UPXFilter scans uncompressed and compressed file

Corbicula Anti Virus is a GNOME HIG compliant front end for ClamAV.

Corbicula Anti Virus tries to be the simplest possible anti virus application, without any fancy features who nobody uses anyway...
