1. About this mini-FAQ
This mini-FAQ informs you about currently available antivirus software
and content filtering tools for Linux and other Unix versions.


2. Overview
All listed products do not only search for known Linux-viruses (such
as Staog or Bliss), but also for known viruses for DOS/Windows, macro
viruses or generally-speaking malicious code.
According to the producers, the Linux-version of their av-software
uses the same scanning engine as it is used at the Windows-version.


The product list is divided in four sections:

* on-demand scanner

* virus protection / content-filtering at the eMail gateway
