"There are several Live CD's for system rescue, forensics,
network security and other tasks available, but perhaps less known
is a live CD from Dr.Web, a Russian IT-security solutions vendor.
The CD allows for attempting the rescue of Windows and UNIX systems
and provides a file manager and editor combined with anti-virus
(AV) scanning with a proprietary solution that is in this case free
to use, as in beer. Given that there have been instances where a
virus has managed to inhibit or even destroy parts of an anti-virus
software, a solution running from CD seems a good idea.
"One can also download a trial of the AV software for Linux,
FreeBSD, Solaris, Mac OS X, Novell Netware, UNIX and Kerio mail
servers. The product has several independent databases for virus
and malware detection, for spyware, dialers and what is called joke
programs. The databases update incrementally with often only a few
kilobytes to download, and new add-ons are often issued several
times a day. I find the incremental updating particularly useful.
Last time I used them on Windows -- which is admittedly years ago
-- several of the big-name vendors still made me download the
entire database of 4 MB once a week."
