============================================================================
TO DO:
------
- Add some code to close TCP ports opened by several trojans.
- Add Neurotic Death 1-5 linkviruses. These are highly polymorphic, but
crash on my system if I try to infect some test files. I have received
several infected files already from other persons and will try to find
some solution for these viruses in the near future.
- Try to get and add the old GlobVec linkvirus. The only ones who have it
are Heiner Schneegold (VT-Schutz) and Sönke Freitag (VTC Hamburg), but
both of them currently cannot find it on their old backups :(
============================================================================
xvs.library 33.38 (size: 59.040 bytes)
- Just had to fix two problems with the security code:
a. Timing has been improved to avoid interference with some music
software. Thanks to Paracels/PCB for the report and testing.
b. Expunge of library caused access to deallocated memory in some
rare cases. Thanks to Mikolaj Calusinski for the report and
the excessive beta-testing ;)
- Fixed (hopefully all) MuGuardianAngel hits in the SurveyMemory()
routine. If anyone detects some more, please send me the logs.
Thanks to Thomas Richter for his suggestions about mmu.library,
but I finally found an other solution. And thanks to Sensei for
reporting all his hits.
- Improved speed of SurveyMemory() drastically by skipping similar
recognition routines in just one step if their common requirements
are not available.
xvs.library 33.37 (size: 58.832 bytes)
- Once more added some new security features to the library. It will
now try to self-defend after alien attacks, only if these efforts
fail, the library gets disabled.
- Added recognition for 2 demo files that I call 'Anti-UAE Trojan'.
Their code checks for UAE systems and in case it finds one will
delete important files. Thanks to Jan Andersen for sending the
demos to me.
- Added recognition for a MS-DOS strain of 'Bastard Installer'.
Thanks to Jan Andersen for the file.
- Added recognition and repair code for 'Bobek 3' linkvirus.
Thanks to Zeeball for sending me an infected file, even though
it was accidentally :-)
xvs.library 33.36 (size: 57.972 bytes)
- After several years on a journey the sourcecodes finally came
back home;-) Yes, it's me (Georg Hörmann) again, still alive
and kicking virus asses... Thanks must go to Alex van Niel and
Jan Erik Olausen for keeping the project alive!
This update was done by me alone, but in the future, Jan Erik
and I will keep the library up-to-date together.
- Rearranged and enhanced the security stuff inside the library
for 100% detection of any (illegal) function patches. Programs
like 'ZeebsVS' will no longer work with this version. Thanks
must go to Zeeball for his demonstration of security gaps in
the older versions.
- Added support for 'IOZ (512 Bytes)' linkvirus. Thanks go to
Zeeball for sending it.
- Added support for 'Rexxfunc' trojan. Thanks must go to Zeeball
and Jan Andersen for sending it.
- Totally redesigned the scanner for virus tasks/processes. The
new code scans all tasks/processes for every known virus in just
one step and can even handle several running copies of one virus
correctly (thanks Zeeball for the hint).
- Checked ALL the stuff that has been added in my absence since
xvs.library 33.18. See below for what I have changed/fixed.
Thanks must go to Jan Andersen, Jan Erik Olausen and Zeeball
for sending me the missing viruses and lots of other stuff.
Special thanks to Zeeball for the ZeebsVS sourcecodes!
- Fixed file recognition for 'Bastard Installer 1'.
- Renamed 'Miami 4.0 Fake Installer' to 'MUI 4.0 Fake Installer',
because that's what it really is.
- Renamed 'CCCP Clone' bootvirus to 'Anal Rapes' (its real name),
fixed its memory recognition and added it to linkvirus brain.
- Removed recognition for 'Doubledensity' bootblock, this is just
an intro boot.
- Fixed longword access to odd address in 'Jode Capullos 2' file
recognition. This caused crashes on 68000 systems.
- Fixed memory removal code for 'Zakahackandpatch' and 'Zakapior'.
The processes of these viruses might stay in memory up to one
minute after they have been detected, that's not a bug, but
their own call to Delay() that we have to wait for.
- Fixed recognition for 'Hitch-Hiker 5.00 Installers' and added
the plain version created by xfdmaster.library 39.13.
- Renamed 'MadRoger Short' to 'NoName (248 Bytes)' to follow the
guidelines of VTC Hamburg (idea by Jan Andersen).
- Renamed '212 Bytes Link' linkvirus to 'NoName (212 Bytes)' and
fixed its memory removal code.
- Renamed 'Explode Trojan' linkvirus to 'Port 9876' and removed
the repair code, we can use 'Fungus' code instead.
- Renamed 'Explode Trigger' filevirus to 'Port 9876 Trigger'.
- Renamed 'Port 4097 Installer' to 'Port 4097' and added memory
removal code for the trojan's process. The process will stay
in memory for a while without doing any harm, see explanation
at 'Zaka...' above.
- Fixed 'Hitch-Hiker 5.00' memory removal code. The process gets
killed immediately, the patched stack addresses will disappear
one by one after a while without doing harm.
- Fixed memory and file recognition and the repair code for
'Motaba 3' linkvirus. Now it restores the correct library jumps
and can repair even files that have been damaged by the virus
(bad branch offsets!).
- Fixed memory and file recognition and the repair code for
'Bastard' linkvirus. Now restores all patched functions (inside
asl.library and VirusCheckerII) and repairs even big files with
bad branch offsets.
- File recognition for 'Bastard Installer 2' will now only detect
the plain, uncrunched virus as xfdmaster.library unpacks this
file correctly.
- Fixed brain entry of 'Port 2421' linkvirus (wrong virus length)
and added memory recognition. Moved 'Port 2421 Installer' from
linkvirus to filevirus brain as it cannot reproduce itself.
- Fixed 'Smeg 2a' and 'Smeg 2b' memory removal code. The processes
get killed immediately and the patched stack addresses disappear
one by one after a while without doing harm.
- Fixed repair code for 'Penetrator 2001' linkvirus to handle both
ways of infection and added memory removal code (removes the task
and 2 of 3 processes, the other one usually should already have
been run out or crashed because of bad coding!).
- Fixed memory recognition for 'Bobek 2' linkvirus and tuned the
file recognition/repair code. Thanks to Jan Erik Olausen for his
bug report about the beta-release of this code.
xvs.library 33.35 (size: 58.512 bytes)
- Added Bobek 2 Installer 1 datavirus.
Thanks to Rafal Mania for sending me this file.
xvs.library 33.34 (size: 58.424 bytes)
- Replaced the Hitch-Hiker 5.00 detection/removal code.
Thanks to Georg Hörmann for writing a better code ;)
- Cleaned up some code. Got some tips from Georg.
So the library is a bit smaller now...
- For developers: Added XVSLIST_DATAVIRUSES to xvsCreateVirusList()
so that you can view data viruses as well.
xvs.library 33.33 (size: 59.756 bytes)
- Fixed 2 bugs in Hitch-Hiker 5.00 removal + improved checking.
Thanks to Thomas Klein for reporting the bugs.
- Removed Sinister Syndicate 1/2 and French from the
bootblock recog. They were harmless.
Thanks to Dirk Stöcker for telling me.
xvs.library 33.32 (size: 59.824 bytes)
- Argh... Fixed major bug in Hitch-Hiker 5.00 removal.
The virus was removed, but the file was not fixed.
Thanks to Jean Holzammer for reporting this bug.
xvs.library 33.31 (size: 59.824 bytes)
- Improved the Hitch-Hiker 5.00 Link virus.
Should be able to detect 99.9% of this virus now...
Thanks to Jan Andersen and Treveur BRETAUDIERE for the files
- Fixed bug in recog for Bastard Installer 1 File virus
- Added recog for 'EICAR STANDARD AV-TEST FILE'
This is not a virus, but a testfile that can be found on
http://www.eicar.org/anti_virus_test_file.htm
The purpose of this test file is to check that your favourite
anti virus program really finds it! Deep inside arhcives etc...
PS! This is a data file, so you might turn on the
'data file checking' in your virus killer.
Thanks to Sami Rautiainen for telling me about this file.
xvs.library 33.30 (size: 58.140 bytes)
- Added Jode Capullos 2 Trojan file virus
Thanks to Fabrizio Bartoloni for the file
- Renamed MKG to Jode Capullos 1
- Added Hitch-Hiker 5.00 Installer file virus
This is the same for all three link viruses

Thanks to Jan Andersen for reporting this.
- Added Bobek2 Installer File virus
Thanks to Fabrizio Bartoloni for telling me about this file.
- The library has changed programmer, although Georg does keep all
copyrights and remains owner of the sources, I (Jan Erik Olausen)
will continue developement. See the README file for my contact
address.
Thanks to Georg Hörmann and Dirk Stöcker for helping me out with
fixing bugs in the source. I couldn't have done this without there
help :o)
xvs.library 33.24 (size: 52.916 bytes)
- Added 4kIntro Trojan
Thanks to Ryben Kozlak and Jan Andersen
- Added Dkg-Blum Trojan
Thanks to Peter Gordon, Urban Mueller and Jan Andersen
NOTE:
This trojan also replaces or adds a file called asi.library.
XVS will not (yet) be able to detect this file because as far as
I could analyze it, it looked like a normal VideoTracker file.
If XVS would have to see this as a virus, more VideoTracker files
will be fake detected. If you have problems or want this added
anyway let me know.
xvs.library 33.23 (size: 52.868 bytes)
- Added Port 4097 Installer (LoadWB) virus
Thanks to Zeeball for the files
No memory infection found yet, might be added later if one
is found.
- Added Port 4097 Trojan (RexxFifo.Library) virus
Thanks to Zeeball for the file
No memory infection found yet, might be added later if one
is found.
- Added Port 2421 Installer virus (Jizzer)
Thanks to Zeeball for the file
No additional memory or file infection found yet, might be added
later if one is found.
- Added Port 2421 Trojan (Mount) virus
No additional memory or file infection found yet, might be added
later if one is found.
These viruses create TCP/IP ports in memory. If a file infected with
one or more of these viruses is found on your system, chances are
that these ports are open already. For now, you should let the
xvs.library remove the virus and then reset your Amiga. (Which is
always a good idea after detecting a virus, but that aside of the
subject) The ports should then be gone.
xvs.library 33.22 (size: 52.732 bytes)
- Added 8x8 Link virus.
Thanks to Jan Andersen, Chill and Zeeball for the files.
Thanks to Heiner Schneegold for the info on this virus.
xvs.library 33.21
- Added YamPPCpatch Trojan. When so called "patched" a file called
"cedmacros" is put in your "S:". Aferwards, when you press
specific buttons in CED ("a", "q", etc.) some lame text is placed
in the text you are editing. Highly annoying. The library
recognises the "patch" and it's installer. Thanks to Jan Andersen
for supplying it to me. Thanks to Urban Mueller for reporting it
to Jan Andersen.
- Changed position of DoubleDensity bootblock virus in virus list.
Wasn't sorted alphabetically properly.
- Fixed MUI 4.0 (clickforcolors) entry to a smaller entry (too big
a name for some virus killers)
xvs.library 33.20
- Quickly fixed the naming of the MUI 4.0 fake. I accidentally named
it Miami 4.0 for some reason. Thanks for Dirk Stöcker for noticing
this.
- Placed the Amos Joshua trojans at the right place in the list for
programs that don't sort the virus list before outputting to the
user.
xvs.library 33.19
- Added Zakapior trojan virus and it's Dropper, thanks to Jan
Andersen for sending them.
- Added Amos Joshua trojan virus and it's Dropper, thanks to
Jan Andersen for sending them.
- Added Amos Joshua Clone virus and it's Dropper, thanks to
Jan Andersen for sending them.
- Added MUI 4.0 trojan virus and installer, thanks to Jan Andersen
for sending them.
- Added AmigaE modules to archive, including a small example.
The modules and example were created by Andrew Cashmore
(aj.cashmore@ukonline.co.uk)
- The library has changed programmer, although Georg does keep all
copyrights and remains owner of the sources, I (Alex van Niel)
will continue developement. See the README file for my contact
address.
xvs.library 33.18
- Fixed bug in recognition code for Elbereth 1 - 4 and Disnomia
linkviruses. Some copies have not been detected correctly.
Thanks to Dran/Chew-Z for the report and the testfiles.
- Added additional verification code for pseudo-executables like
'Scalos.key' starting with $3f3 even if they are datafiles.
Thanks to Ramon for the report.
xvs.library 33.17
- Added 'STD Crabs #1' linkvirus and its Dropper. Thanks to Jan
Andersen and David Knell for sending them.
- Added 'STD Vaginitis #1' linkvirus and its Dropper. Thanks to
Jan Andersen for sending them.
- Added 'STD Vaginitis #2' linkvirus, its Dropper and
'STD Vaginitis #3' filevirus. Thanks to Jan Andersen and
Jesper Svennevid for sending them.
xvs.library 33.16
- Added another security mechanism that should bring up an alert
if xvs.library has been modified in length (what usually all
viruses do). If such an alert pops up on your computer, please
perform a file check with VirusZ on 'xvs.library' in your libs:
drawer. The library will therefore no longer refuse to work when
it's (possibly) infected.
- Oh my god, why am I such an idiot? While analyzing Polish Power
linkvirus, it suddenly came to my mind: The polymorphic code
of Polish Power is exactly the same as the one Antonio uses.
I just had to fix some small routines in the repair code, and
now both dangerous linkviruses will be recognized :-)
xvs.library 33.15
- My Christmas gift for you: Recognition and repair code for the
'Antonio' linkvirus (that's how I call it!). It uses the ugliest
polymorphism I have seen so far, but I nevertheless did it in
just 2 days. If there appear infected files that cause problems,
please send them to me immediately (by email if possible).
Thanks to Jan Andersen for sending me this virus so quickly.
xvs.library 33.14
- Added 'Datatypes.Library Trojan'. Thanks to Jan Andersen for
sending this Miami backdoor.
- Please note my new email address in the README file.
xvs.library 33.13
- Added Mad_Roger Short linkvirus.
- Added Robby bootvirus. Thanks to Peter Lindberg for this really
old stuff. It's from 1988 and I've never seen it before!!!
- Added 'C' developper files. Thanks to Dirk Stöcker for creating
them.
xvs.library 33.12
- Added new linkvirus: Fungus/LSD. Thanks to Jan Andersen for
sending this stuff.
xvs.library 33.11
- Added new viruses: UnpackJPEG Trojan, LOBO Simple, LOBO Weird
and its Installer. Thanks to Jan Andersen for sending the viruses
and Dran/Chew-Z for sending them to Jan.
- Finally released the developper files (include, autodoc, fd etc.)
to the public. It's time now to give other skilled coders the
opportunity to develop their own viruskillers...
xvs.library 33.10
- Added the rest of the missing viruses from VTC (see below):
666!-Trojan, Mosh 1.0, Promoter 1, Purge Dropper, Purge Trojan,
TDTJ Trojan, SehrJung Dropper, SehrJung Trojan, Nibbler 1.0ß Link,
Nibbler Installer, New Age (bad linkvirus, can only be deleted).
- Added recognition for 666!-Trojan damages to sector check code.
- Added recognition for files damaged by Cute Little Ponnies and
Inspector X of A.L.F.
- Added AmigaRAR.exe Fake, a packed version of Gathering '95 that
cannot be decrunched by xfdmaster.library at the moment. I will
add the cruncher as soon as possible to xfd.lib, then the extra
recognition is no longer needed. Thanks to Jan Andersen for this
packed trojan.
xvs.library 33.9
- Finally I contacted Soenke Freitag of VTC Hamburg and asked him to
send me the old but still missing viruses from their test. I added
the following viruses until now:
AHM Keymaker 1.1, BBS Blieb6, Miami Fake, BBS MegaMon, DumDum 2,
BBS CLP/InspectorX, BootX Updater, Buzz Bomb MKI, Hexer/Bea 1,
Hexer/Bea 2, Hexer/Bea 3, Conman Format, Compuphagozyte 13,
Disk.info Bomb, Joshua 3 and Christmas Violator.
There are still more to come, I will add them (hopefully) in the
following 2 or 3 weeks.
Special thanks go to Soenke Freitag for the good cooperation and
all the work he had with sending me the virus collection.
Thanks must go to Markus Schmall and Jan Andersen too for giving
Soenke the permission to submit the viruses to me (most of them
were NDA).
- Added MaxDoorControl + Lib. Thanks to Jan Andersen for sending it.
xvs.library 33.8
- Added Mad Roger bootvirus and WAWE trojan. Thanks to Jan Andersen
for sending the trojan.
xvs.library 33.7
- Did some internal reworking for better performance.
- Added bootblock viruses: AHC, Gadaffi 2, Virus Slayer 6.12.
- Added recognition for files damaged by Lisa FuckUp 2.0.
- Fixed removal code for ZIB linkvirus. Now detects all files that
have been infected by the installer directly.
- Added recognition for Doom_CLX Trojan, CompuPhagoLink and
X-Ripper 1.1.
Special thanks for sending all the above mentioned viruses are going
to Jan Andersen. VirusZ did not recognize these viruses at the time
when the VTC-Test 1998 took place, therefore the ranking of VirusZ
in this test would be even better right now.
xvs.library 33.6
- Added HappyNewYear 96/2 clone, HNY 96/3 clone + installer and
Sepultura bootblock virus. Thanks to Jan Andersen for submitting
them.
xvs.library 33.5
- Fixed bug in 'Smeg' recognition. Thanks to Thomas Richter for the
tests and the report.
- Added 'MKey.exe Fake' trojan. Thanks to Jan Andersen for sending
it to me.
- Added 'HANF' linkvirus. This nasty bastard took me a lot of time.
Thanks to Ralph Bernecker and Jan Andersen for sending it to me.
xvs.library 33.4
- Added 'ReOrgIt Fake' trojan. Thanks to Jan Andersen for sending
it to me.
xvs.library 33.3
- Added new viruses: 'Death To Maxs' 1-4 trojans. Thanks to Jan
Andersen for sending them.
- Rewritten some memory checking routines for safer execution.
xvs.library 33.2
- Just did a little fix in the memory checking code. Some strange
patches haven't been accepted.
xvs.library 33.1
- Moved all virus recognition and removal code from VirusZ to
this library. Several support routines have been rewritten
or designed totally new.
