New versions of F-Prot Antivirus for UNIX released

5 March 2004

New versions have been released of all F-Prot Antivirus products for UNIX based platforms. The version number of F-Prot Antivirus for Linux x86, BSD x86, Solaris SPARC, Solaris x86, AIX on IBM pSeries and Linux on IBM zSeries is now 4.4.0

These newest versions of F-Prot Antivirus have been released in response to the multiple outbreaks of recent days and provide improved scanning of encrypted executables and password protected ZIP archives. The improved scanning technique provided in these versions allows F-Prot Antivirus to better detect potentially damaging executables hidden in these archives and to flag them as such.

In addition, scanning of all archives, whether password protected or not, is now a default setting in these versions of F-Prot Antivirus. This setting can be changed by users and network administrators. More information on modifying settings can be found in the F-Prot Antivirus for UNIX man pages.

These changes effectively constitute a raising of the security standard by which F-Prot Antivirus scans and sorts attachments. However, these safety measures may result in a small number of false positives if legitimate executables of a certain length are sent within password protected ZIP archives. Users should therefore be wary of sending executables in this manner and seek other means of transporting such files.

We recommend that users of F-Prot Antivirus for Linux x86, BSD x86, Solaris SPARC, Solaris x86, AIX on IBM pSeries and Linux on IBM zSeries systems update their programs to these newest versions as soon as possible.
