New versions of F-Prot Antivirus for all UNIX based platforms released.

22 December 2004

New versions of F-Prot Antivirus for all UNIX based platforms have been released. The version number of F-Prot Antivirus for Linux x86, for BSD x86, for Solaris SPARC, for Solaris x86, for AIX on IBM pSeries and for Linux on IBM zSeries is now 4.5.0.

In preparation for the release of versions 4.5.0, the F-Prot Antivirus scanning engine has undergone a major overhaul with a number of improvements and the addition of some important new features.

The detection capabilities of F-Prot Antivirus for UNIX have been enhanced in version 4.5.0 with better detection of executable packers, often used by malware authors to conceal malicious code. Also, the new scanning engine introduces greatly improved heuristic capabilities. F-Prot Antivirus is therefore better equipped to detect and neutralise malware that may attempt to compromise a system in the interrim period after a new threat appears but before virus signature files have been updated. As a result, F-Prot Antivirus now provides UNIX users with an unprecedented level of security and protection against viruses, worms and other malware.

Handling of so called "archive bombs" has also been significantly improved in these new versions. "Archive bombs" are archives that cause scanners or other programs to crash or hang because of intensive resource consumption during the scanning of hundreds of levels of archives within archives. The F-Prot Antivirus for UNIX scanner now scans only a predetermined number of levels deep into nested archives of supported types in order to protect against such "archive-bombs".

Versions 4.5.0 of F-Prot Antivirus for UNIX also include a number of important bugfixes and some minor modifications, all geared towards enhancing the user experience and the protection we provide our UNIX customers.

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 versions 4.5.0 as soon as possible.
