For a commercial solution, check out "Vexira Antivirus for Linux": http://www.centralcommand.com/linux_workstation.html For a free solution, check out http://clamav.elektrapro.com/ (it's still in an early stage but it's good that it's based on Open Antivirus). Open Antivirus themselves have several projects including Java-based anti-virus toolkits which you can find at: http://www.openantivirus.org/projects.php Haven't tried any of these out but if you do, tell us what your impressions are.

The link on the web site for Knoppix 3.1 does not work (http://www.knopper.net/knoppix/index-en.htm) because you forgot an l at the at the end of the URL. It should be http://www.knopper.net/knoppix/index-en.html
