Free anti virus scanner software for linux

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.

Aegis project is a virus scanner for Linux, Unix and Windows with a simple and intuitive user interface.

Aegis supports scanning of subdirectories, hidden files and .zip and .tar archive files, and drag-and-drop of files from the Nautilus file browser, or your Gnome desktop. When a virus is detected you can choose to delete, quarantine or rename the file.

POP3 Virus Scanner Proxy is a full-transparent proxy daemon which scans all mails for viruses using third party scanners (built-in support for AVPD and Trophie).

You have to set up a port redirection in the linux-netfilter (iptables) so that all connections from e.g. inside your office to any POP3 server outside in the world will not leave your router, but come a local port, on which POP3VScan listens. POP3VScan receives from the linux kernel the original destinations of packets (the POP3 server outside in the world) and will connect to them.

All data we receive from the client will be sent to the server, and vice versa. With a little enhancement: we parse the neccessary parts of the POP3 protocol and when an email is sent from the server, we store it into a file, invoke a virusscanner and send it if it is good, or we just replace it with a virus notification. It should be possible to use all scanners using the scannertype=basic. Also POP3VScan provides scannertype=avpd for high-speed scanning using Kaspersky Anti-Virus for Linux, every C programmer can easily adept other scan-daemons (trophie, sophie, antivir, ...).

Neither the client nor the server has to be configured, none of them will take notice that theres a mailscanner (except the client when he gets a virus notification or if he looks into the header, and the server gets our ip as source).

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.

samba-vscan provides on-access scanning of Samba shares with ClamAV (clamd and libclamav), F-Secure AV, FRISK F-Prot Daemon, Kaspersky AntiVirus, OpenAntiVirus.org ScannerDaemon, mks AntiVirus, NAI/McAfee VirusScan, Sophos Sweep (via Sophie), Symantec AntiVirus Engine (via ICAP), and Trend Micro (via Trophie). It supports Samba 2.2.x/3.0.x.
samba-vscan currently is made of ten Samba VFS modules:
vscan-fprotd - for use with F-Prot Daemon
vscan-icap - for use with an ICAP anti-virus service, currently only Symantec AntiVirus Engine 4.x is supported (this is alpha code and not yet for production environment!)
vscan-kavp - for use with Kaspersky AntiVirus (kavdaemon) via Kaspersky KAV client C library. vscan-kavp is a stripped-down version from vscan-kavp of Ries van Twisk). For the full-featured version please see http://www.rvt.dds.nl
vscan-mks - for use with mks32 via mks_vir Daemon
vscan-oav - for use with OpenAntiVirus.org ScannerDaemon
vscan-sophos - for use with Sophos Sweep via Sophie (http://www.vanja.com/tools)
vscan-trend - for use with Trend Micro FileScanner / InterScan VirusWall via Trophie (http://www.vanja.com/tools)
vscan-clamav - for use with Clam AntiVirus Daemon (clamd) or libclamav (http://www.clamav.net)
vscan-nai - for use with NAI/McAfee uvscan
vsan-fsav - for use with F-Secure AntiVirus (daemon)
vscan-symantec - for use with Symantec Anti Virus Engine Note: the vscan-symantec odule will statically linked against the symantec library. This lib is not covered by GPL and the resulting vscan-symantec VFS module may infringe the GPL of Samba! Due this reason, the vscan-symantec module will only be build if --with-symantec flag is used for ./configure
Enhancements:
- NEW, VERSION, ChangeLog: updated
- icap/vscan-icap.c: bugfix
- Released samba-vscan 0.3.6b

Port Scanner provides a tool to check for open ports.

Port Scanner will try to connect on every port you define for a particular host. If a connection is made, it will try to read any data returned.

This product is intended for individuals to test their own equipment for weak security, and the author will take no responsibility if it is put to any other use.

Amazon sell many books on Security that will enhance your ability to keep your computer secure.

The Windows version has been withdrawn. Apologies for this, but it is too popular and uses my bandwidth up too quickly. If anyone want to host the binary for me, I will happily post a link here. It should also be possible to compile Version 2.1 for Windows.

Whats New in this release:

.(QT) Takes multiple port ranges.
.Minor bugfixes.
