- V1.17 2nd-Feb-98 (Now a DiGiTaL CoRRuPTioN production. :-)
- ~~~~~~~~~~~~~~~~~
- - The taskname changer and memory checker only worked if the FVK window
- was activated, as it was relying on IntuiTick IDCMP events.
- This has now been changed to use a timer device routine.
- This was actually quite a lot of code changing, and now creates its
- own message port instead of using the one provided by OpenWindow()
- - Before, if a file was crunched, it was decrunched, and then checked.
- If this file had been infected after it was crunched, sometimes the
- virus wouldn't be detected, as the xfdmaster library still recognised
- the crunch header even with the virus-code appended.
- Now FVK now checks like this..
- Check file.
- Try to decrunch file.
- If file was crunched, check it again.
- This means crunched files are checked (very) slightly slower than before,
- but this is the only way in which to be completely safe.
- Thanks to RaMoNsTeR/dC for pointing out these two bugs :-)
- - FVK now _NEEDS_ xfdmaster.library installed.
- - Now handles files with debug hunks in straight after the header correctly.
- AX_Fucker recognition now works again.
- - BGS9 file-detection improved.
- - Improved boot-virus engine.
- - Added AEK clone, FILO 5.31, French.
- - Added HNY98 Bootblock. (Thanks to John Adams for sending this to VHT)
- - Improved recognition of VKill1.0, Australian Parasite, Coders Nightmare,
- Divina Exterminator, GX Team, Gremlins89, NorthStar1, PentagonCircle2,
- RevengeBootLoader, TimeBomb10, Joshua2, SwitchOff
- - If the boot is not identified, it now computes the checksum, to make
- sure it's valid, If the checksum is incorrect, then it's rescanned
- against the database using the corrected checksum.
- - Now recognises bootblocks that are DOS1 thru DOS5.
- - Removed some unused text strings and some unused variables.
- - When a virus was removed from a file, the filebuffer was never freed
- from memory. This memleak now fixed.
- - Menus now appear in V39 mode.
- - No longer crashes if xfd.library isn't installed.
- - Shell file-check used xfd.library after it was closed. This could have
- caused a crash if xfd got expunged.
- - Most filevirus checks read past the ends of the filebuffer, which is bad.
- Now, no reads are performed that are larger than the loaded file.
- - Added Commander virus and its Installer on request by Jan Anderson.
- (Memory kill will be added next time)
- - Main event-handler restructured & optimised.
-
- ----------------------------------------------------------------------------
- V1.16 7-Jan-98 (Fastest update ever :-)
- ~~~~~~~~~~~~~~~~
- - Added Happy New Year 96 [Optimised] & it's installer.
- This was released as source code, so I don't know if it's in the wild.
- But its added just in case.
- - Added a fix for a stupid problem in my HNY98 removal code which caused
- an infinite loop to be entered with some files.
- - Rewrote the Happy New Year 96 file recognition.
- - Now based upon code recognition instead of the text, which makes
- it recognises the `Fucked Up Year 98' clone, and maybe any others
- which may be hanging around.
- - Fixed a problem, where some files it fixed still had BRAs to a
- virus which was no longer there.
- - HNY96 & HNY98 now use the same routine to fix up the patched BRAs.
- which saves a few bytes
- - Changed `This file is the xxx virus' to the better description of
- `This file is infected with the xxx virus'
- Thanks RaMoNsTeR^DC for this `bug-report' :-)
-
- ----------------------------------------------------------------------------
- V1.15 6-Jan-98
- ~~~~~~~~~~~~~~~~
- - Added Happy New Year `98 filevirus and Anti-Cracker bootblock.
- Thanks RaMoNsTeR/DC for the fast supply.
- - Added a new file classification. "Joke" files.
- First entrant into this new catagory is `ViriCheck'.
- Please stop writing such crap, and do something constructive.
- The anti-virus field is something to be taken seriously and does
- not need such foolishness.
- - Reclassified `DriveMusic' as a Joke file.
- - Now prints the date & time of filecheck completion, and how many
- files were scanned. (Sorry this took so long, but I've been busy)
-
- ----------------------------------------------------------------------------
- V1.14 22-Dec-97 (Yet another fix)
- ~~~~~~~~~~~~~~~~~
- - My ZIB removal code was breaking most files, as it wasn't repairing all
- the branches to the virus code, only the last one in the file.
- Sorry for any damaged files.
- Thanks to Alex Van Niel for the info and to my friends in DC for the
- example files.
- - All file check routines overhauled to handle large code hunks.
-
- ----------------------------------------------------------------------------
- V1.13 5-Dec-97
- ~~~~~~~~~~~~~~~~
- - Added ZIB Installer.
- Thanks to Jan Anderson for this.
- - Fixed BioMechanic6 Recognition, sorry to anyone who deleted any files
- due to this mistake, but I had only one executable to work from :-(
- Thanks to the guy who sent two examples (Sorry, forgot your name ;-( )
-
- ----------------------------------------------------------------------------
- [ I've been even busier with University stuff than ever,
- [ so I've not added anything to FVK recently.
- [ However, New viruses get priority so here it is.
-
- V1.12 29-Nov-97
- ~~~~~~~~~~~~~~~~~
- - Added ZIB file virus.
- Thanks to Harry Sintonen for this monster.
- - Added Zombi Bootvirus
- - Fixed Joshua bootvirus recognition
-
- ----------------------------------------------------------------------------
- [ Quite some updating/fixing/improving this time.
- [ I've actually been really busy with University stuff, plus I was ill
- [ for a little while, so that's my excuse for this slowness of late.
-
- V1.11 15-Oct-97
- ~~~~~~~~~~~~~~~~~
- - Improved File-checker :
- - Added LiSA-Fuckup 3.0 (ScanEbola97) trojan
- - Added some old viruses : AFFE, Aram-Dol, AX-Fucker, Biomechanic 6,
- BBS-Traveller (Ebola2)
- Thanks again to Jan Anderson/VHT DK for these old beasts.
- - Some viruses wouldn't have been detected if they had their RELOC hunks
- converted to short relocs.
- - Now asks before cleaning/deleting a file, this was actually harder
- to implement than it sounds, and quite a large part of the filechecker
- had to be rewritten.
- - Shell Filecheck can now be aborted with Ctrl-C.
- - FileInfoBlock is now only allocated once per file check, before it was
- allocated and deallocated each time for every file.
- This should speed the FileChecker up a little.
- - Filechecks used to walk past end of buffer occasionally.
- - Incorrect file buffer size was FreeMem()'d
- - Now strips HUNK_DEBUG, HUNK_SYMBOL, & HUNK_NAME before file check.
- - Some viruses which can only be deleted were calling DeleteFile() instead
- of branching to a FastKiller routine, which sets the protection bit first.
- This also made the code a little shorter.
- - Removed some unnecessary tests in a few file-checks.
- - Removed enforcer hit that occured if an xfd error occured.
-
- - Improved bootblock analysis engine:
- - Added some old viruses : BootAIDS, ByteBandit4, COBRA, Cheater Hijacker,
- DigitalLife2, Disgust, DATACrime, Cracker Exterminator, Devils, Dr Mosh,
- Dr Mosh2, ELENI, Executors, Fast Eddie, GeneStealer, HEIL, Indiana Jones,
- Influenza, Infector, INGO, IRAK 3, Lamer Exterminator Decoded, LameStyle,
- Love Machine `90, Loverboy, Little Sven, MG, Nuked007, Obelisk (Format),
- Paratax III, PayDay, Perverse I, Plastique, Red Ghost, Sao Paulo,
- Sachsen 1, Sinister Syndicate 1.0, SS, SHI, Sonja, Starlight 2,
- Starlight Warhawk, Suicide Machine, TNK, TTS, TFC Revenge,
- Tomates-Gentechnic2.0, Unknown1, Virus-Fighter, VirusV1, VIPHS,
- ZAccess 3.0
- Thanks to Jan Anderson/VHT DK for those.
- - Fixed recognition for CCCP, DiskDoktors, NorthStar2, SwitchOff & Incognito.
- - SCA Clones are now called just that to save memory.
-
- - Tidied the line-indenter a little.
- - Misc code shuffling to group associated routines, which meant a few
- branches are now optimised to byte distances. Ie, shorter executable.
- ----------------------------------------------------------------------------
-
- V1.10 22-Sep-97
- ~~~~~~~~~~~~~~~~~
- - First GUI Version! Major overhaul of several routines.
- So far, just main GUI, and FileCheck GUI included.

- Happy New Year 96, Happy New Year 97.
- Thanks to Jan Anderson/VHT DK for those.
- - Reworked HitchHiker 4.11 detection
- - Small optimisation in file detection.
- - Fixed 3 small bugs in memory clean.
- - Was reading from the wrong Trap vector.
- - Wasn't freeing the memory the virus occupied.
- - When virus removed from memory, the `removed' message looked a
- little odd. Now fixed to look like the others.
- - Reworked hunk-handler
- - No longer crashes when an exe with no HUNK_CODE's is found.
- - Handles hunks with zero bytes correctly now.
- - Optimised the routine which shortens hunks.
- - Removed possible enforcer hit in filecheck.
- - If a file-error occurs, a linefeed is now printed too.
- - When xfdmaster.library returns an error, this text is now printed.
- - Recoded the text-indenter.
- - Shortened file detection routines for BOKOR 1.1 and HitchHiker2.01
- - Dirwalker now works with single files.
- - Added Workbench startup code, Tooltypes will be added later.

- ----------------------------------------------------------------------------
-
- V1.8 1-Sep-97
- ~~~~~~~~~~~~~~~~~
- - Added UnhappyNearlyNewYearSummer97 installer & dropped file.
- Thanks to Adam Polkosnik for this shit.
- This is a compiled REXX script supposedly written by me.
- I'd love to meet the asshole who made this lame shit.
- This didn't even run on any of my systems, so I was unable to produce
- any infected files.
- - Converted docs to AmigaGuide format.
- - Added a list of known viruses with explanations.
- - When HitchHiker 2.01 was cleaned from a file, too much of the buffer
- was saved, and may have created some unloadable files.

- - Added VMM3.3 & KBVirus to LoadSeg() tunneler.
- ----------------------------------------------------------------------------
-
- V1.7 28-Aug-97

- - Fixed MAD2 bootvirus detection.
- - Added XFDPatch to the vector tunneller
- - DirWalker wouldn't abort on Ctrl-C.
- - DirWalker didn't obey the QUIET argument.
- - If a virus was found in a crunched file, and the QUIET arg was specified,
- then no text would be printed.
- - Now restores filedate when removing link-viruses.
- - FVK now sets the Read & write file protection bits when removing a link
- virus from a file, and restores the original status afterwards.
- - Removed all inline file-delete's, and replaced them with Bsr's to a
- DeleteFile routine which sets the Delete bit first.
- - Optimised filecheck routine a little, to use jumptables instead of
- multiple compares.
- - Boot analysis engine sometimes exited before completing the scan which
- meant some bootviruses were reported as clean.
- - Bootblock analysis engine sometimes got stuck in an infinite loop.
- - Outputs some error-messages if the something goes wrong during filecheck.
- - Selfcheck would fail if started from DirectoryName/FastVirusKiller
- - BOKOR 1.05 and BOKOR 1.06 are virtually identical to check for, so now
- they use just one removal routine, (They are both reported correctly though)
- - Fixed version string.
-
- ----------------------------------------------------------------------------
-
- V1.6 22-Aug-97
- ~~~~~~~~~~~~~~~~~
- - Self-check routine now uses a larger buffer for pathname.
- - Added a variant of Harry Sintonen's DirWalker routine.
- The script is no longer necessary.
- - Rewrote text output routines.
- They now generate a buffer, and print that all in one go,
- instead of printing each line in three stages. (filename, packer, virusname)
-
- ----------------------------------------------------------------------------
-
- V1.5 17-Aug-97
- ~~~~~~~~~~~~~~~~~
- - Added BOKOR 1.1 virus.
- - Added Xtruder 3.5 trojan.
- - Added Drive-Music `joke'.
- - Added Bootfile analysis engine.
- This beauty is really fast. I don't believe it can be done any faster
- way. And it won't slow down much when more bootviruses are added to it.
- - Added over a hundred bootviruses to the bootfile engine.
- - Tidied docs a little.
- - Program now does a self-check, and removes any link-viruses that may have
- been attached to it.
- - Removed the `FastKiller FastKiller' line from the script.
-
- ----------------------------------------------------------------------------
-
- V1.4 11-Aug-97

- V1.3 10-Aug-97
- ~~~~~~~~~~~~~~~~~
- - Corrected some strings.
- BOKOR 1.01 was reported as 1.0, and 1.05 as 1.01
- - Added BOKOR 1.06 virus.
- - If NOSAVE was specified, and a virus was found, an infinite loop occured.
-
- ----------------------------------------------------------------------------
- V1.2 26-Jul-97
- ~~~~~~~~~~~~~~~~~
- - Added recognition for 5 more fileviruses.
- - BOKOR v1.01 (Thanks to Olli-Pekka Kaikuaho for that one.)
- - HitchHiker 2.01
- - HitchHiker 4.11 (Thanks to Dave from IRC #Amiga for that one.)
- - VirusMaker1.0
- - TimeBomb 0.9
- - BGS9
- - Saddam 1
- - Improved File-scanner.
- - Some internal changes that make it easier to add new viruses.
- - Now handles more hunktypes Should now cause no crashes while scanning.
- - If a virus is removed from a file, it now tries to decrunch the cleaned
- file before rescanning.
- - Sometimes didn't free filememory. Now fixed.
- - Didn't scan new file after removal of a virus, but instead, a
- messy-buffer, file is now reloaded.
- - Fixed FreeMem() bug.
- - Now handles Zero-byte hunks.
- - Rewrote reloc-hunk parser.
- - Filescanner code wasn't reentrant, now fixed.
- - Script now scans C:Protect too, in case the user used it to set the script
- bit of `ScanDirs' while a virus was active.
- - Improved Memscanner
- - Improved recognition of BOKOR v1.05
- - If there was more than one virus in memory, FVK went into an infinite
- loop. This has now been fixed.
- - Now recognises PPLoadSeg and SegTracker, and tunnels them to get the
- LoadSeg vector before they patched it. If a virus is found after
- tunneling, The Vector previous to it will be restored.. Imagine..
-
- ROM VECTOR
- Virus
- SegTracker
- PPloadSeg
-
- After tunneling PPLoadSeg and SegTracker, the virus is found, and the
- ROM vector will be set, so effectively, SegTracker & PPLoadSeg will be
- removed.
-
