During the last years, I still got user requests from time to time to either
update VirusZ and xvs.library for AmigaOS 4.x or release the source codes to
So as we saw the 30th anniversary of VirusZ in 2021, I actually decided to
update VirusZ and xvs.library once again for all Amiga(-like) systems that
popped up over the last 15 years, but unfortunately had to notice that I
couldn't find the last backups of my sources any more. So at first a very
special "thanks a lot" to the CBM Museum Wuppertal and Patrick Brough who
could restore all files from the original harddisk of my old A3000 (which is
severely damaged by battery acid). Without their help, the project would
have been dead forever!
During the last months, I had to understand the (undocumented) new features
of AmigaOS 4.x (especially the memory management), analyse parts of AROS and
do a lot of beta-testing. Therefore I installed WinUAE with several
emulated Amiga systems and OS versions (I finally bought AmigaOS 4.1 and
3.2, but currently don't have 4.0 and 3.1.4 which aren't available any
more). Special thanks to Hubert Maier, Costel Mincea, Thomas Frieden, Almos
Rajnai, Stefan A. Haubenthal, Christoph Fassbach, s.hawamdeh and all the
others that gave me information about OS 4.x and did some tests on their
So this is one of the first releases after 15 years and should run stable
now on all AmigaOS, MorphOS and AROS systems. But please don't hesitate to
report problems if you still encounter any.
1. Legal Stuff
This software package has been developed and is copyright © 1997-1999 by
Georg Wittmann. Changes and updates from December 1999 to May 2001 are
copyright © 1999-2001 by Alex van Niel. Changes and updates from June 2001
to October 2001 are copyright © 2001 by Jan Erik Olausen. Releases since
October 2001 are again copyright © 2001-2022 by Georg Wittmann.
No parts of this software package may be altered by any means (this includes
editing, reprogramming, crunching, resourceing etc.), except archiving. The
author is in no way liable for any changes made to any part of the package,
or consequences thereof as he is in no way liable for damages or loss of
data directly or indirectly caused by this software.
This software package is FREEWARE for non-commercial use. Commercial users
or distributors must gain permission of the author first. Neither fees may
be charged nor profits may be made by distributing this software package.
Outside a single machine environment, you are not allowed to reproduce only
parts of the package, but you have to copy it completely.
The xvs.library contains all the virus recognition and removal code that was
formerly included in VirusZ. This step has been taken for one major reason:
VirusZ, Virus_Checker, Virus_Executor and all the other antivirus software
can be updated quickly without releasing the whole packages every time a new
So simply install the xvs.library from this archive to your LIBS: drawer to
get 100% protection against the latest viruses. You can either copy it by
hand or use the installer script written by David Crawford.
NOTE #1: To detect ALL viruses inside crunched and/or linked files,
xvs.library must be used together with the xfdmaster.library (available from
Aminet or the VHT-Denmark homepage)! I therefore strongly recommend the
installation of this library too.
NOTE #2: If xvs.library detects that it might have been modified (maybe by
some new virus?), it will inform you with an alert and tell you what to do!
3. PGP Signatures
To be able to check if the library in this archive really came straight from
the author, you can use my public key with the .sig files in the archive.
If you are not sure or do not trust the included key, then you can always
request an original copy straight from me (by email, see below) or get it
from the VHT-Denmark homepage.
4. Some Words to Amiga Programmers
As you may have noticed, I don't have enough time to add all the features
that users desire to my viruskiller VirusZ. On the other hand, there are a
lot of talented coders out there who might have the time to write a really
good viruskiller environment, but don't have all the viruses to add them or
are not willing to torture themselves with analysing all those (old) little
That's the point where xvs.library comes in. With this library you get a
powerful tool to detect and eliminate all sorts of viruses. Currently
xvs.library offers you the following functions:
a. Detect bootblock viruses and install clean bootblocks instead.
b. Detect manipulated disk sectors and repair them if possible.
c. Detect infected files and repair them if possible.
d. Scan all memory regions for active viruses and remove them.
All you have to do (and that's still enough, believe me ;-) is to submit the
files, sectors or bootblocks you want to have tested to xvs.library. In
other words: You design an outstanding GUI with all the features that are
required nowadays (ARexx, Locale, etc.) and I support you with my antivirus
knowledge of the last 30 years!
Currently I (Georg Wittmann) am developing the xvs.library package alone
again, so for any bug reports, comments or new ideas just contact me at the
