Free linux virus protection software for linux

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

- SquidGuard
- Jesred
Supported Virus Scanners
- AntiVir
- AVP

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.
