An open beta for Unix is available at http://free-av.de/personal/en/unix/antivir-workstation-pers.tar.gz This is the all-in-one package for Linux/OpenBSD/FreeBSD/Solaris. You have to register here to get a free license file for the AntiVir Unix Classic Edition: http://free-av.com/unixreg_form_en.htm After installation, create an empty file called ".incvdf" in the same dir as the AntiVir executable, e.g. with "touch .incvdf". Important, you must update AntiVir before using this version (--update switch). The incremental VDF beta files are the same as the regular VDF files. Both are updated together, so you have the most recent signatures when using the beta signatures. If you are already using AntiVir Unix Classic edition, you only need to create the .incvdf file to switch over to incremental VDF files. Please send feedback to unix [at] beta.antivir.de A Window beta version will be available at a later point.
