!VKiller/Docs/History
This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.
Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

File contents
Revision History of VKiller --------------------------- V2.20 (May 1991) ---------------- * Added check for Vigay Virus. * Removed the restriction on the number of directory levels - VKiller now requires 1K of RMA per directory level (dirs will be skipped if it cannot be claimed). * Speeded up the check for the CeBit virus by loading the !Boot into a buffer rather than using a temporary output file. * "Fix" CeBit module when detected so it can be safely killed. * Revamped a significant portion of Philip Colmer's code just to make it neater and slightly more efficient :-) * Now only update application icon in dialogue box whilst scanning if it is different from what's already displayed. * Centred the dialogue box the very first time it is opened (but remember its position on subsquent closing/re-opening). * Expanded "...is already innoculated"-style messages to include the application name (e.g. !Edit.!Boot instead of just !Boot). * Removed (for example) "adfs::4." from the beginning of the directory spec shown in the "Dir scan" icon of the dialogue box. This is redundant info because the Filing System and Device icons already display this. * Widened the dialogue box to accommodate longer messages. * Added directory name underneath application icon in the dialogue box. * Added "Files scanned" and "Dirs scanned" icons to the dialogue box. V2.10 (April 1991)/V2.11 (April 1991) (neither version publicly released) ------------------------------------- * Code heavily reworked by Philip Colmer: User interface improved and closer to Acorn guidelines. Support for Econet & NFS added. Logging to a file supported. Application icon in dialogue box now uses standard 'APP' icon if not in RMA. CeBit virus checked for. <Obey$Dir> set to null:$ in the !Run to slow down CeBit infections. Thanks to Fil for taking the time out to greatly enhance the code - there's no way I could ever have done the network code on my own ! * These versions were not released because I wanted to make some further changes on top of Fil's (besides, it took me time to suss his new code !). A couple of minor bugs were also ironed out during this process. V2.00 (March 1991) ------------------ * Received 'new' ArchieVirus from Alan Glover (originally discovered by Hugo Fiennes). After extensive disassembly, detection/innoculation code was added to VKiller. Some of the ideas of the code emanate from Hugo's "Hypothermic" innoculator, but they've been substantially revamped. * Improved error check if !Boot failed to load when checking for the Extend Virus. * Split documentation into multiple files because this file was starting to grow exponentially ! * Revamped the filing system cycling as suggested by Steve Turnbull. * Widened the dialogue box application icon area to cope with wider 256-colour MODE icons. * Increased WimpSlot for the !RunImage from 64K to 80K because of the larger code. V1.20 (January 1991) -------------------- * Improved error checking during a scan - an OS_GBPB error will halt the scan and display the error in the Status field of the dialogue box. An obvious one is "Drive empty", which V1.10 didn't handle at all well ! * Display warning dialogue if user disables the currently selected filing system (e.g. by *RMKilling it). * Display fatal error if no scannable filing systems are detected at any time. * Added an application icon in the dialogue box to reflect the icon of the application currently being scanned (suggested by Philip Colmer). * Applied fixes and improvements to the PROCputdata routine suggested by Philip Colmer. * Managed to narrow the dialogue box despite the new icon. Also subdued the background colour from cyan to a more restful light grey. * Fixed incorrect RamFS handling and added SCSI support (Oak and Lingenuity). V1.10 (December 1990) --------------------- * Now multi-tasks with a dialogue box to select options. Code substantially reworked to support the WIMP (and it took longer than the guts of V1.00 did !). * New patch code to fix Extend Virus 'bug' - now provides safer Wimp_CloseDown calls for 50% of the time. Despite this, RMKilling the module is still riskier than it was with V1.00. * !Boot files to be innoculated that are not terminated by a linefeed (<&0A>) now have that missing linefeed added prior to innoculation. * Extend Virus Execution Count is now displayed just before the module is deleted from the infected disk or killed from the RMA. * Only !Boot files that have the Obey (&FEB) filetype can now be innoculated against the Extend Virus because this is only filetype that makes any 'sense' in the context of the innoculation and is also the filetype used by Extend Virus when it modifies the !Boot, even if it was originally a different type. * If an innoculated !Boot file is being created from scratch and there is no !Sprites file in the directory (with the Sprite filetype), then the IconSprites <Obey$Dir>.!Sprites line is no longer added. V1.00 (November 1990) --------------------- * Written as a plain single-tasking BASIC program which could also innoculate !Boot files against the Extend Virus. * Recurses down directories (to a maximum level of 8) and displays various messages in garish red, green or yellow. * Can remove the Extend Virus RMA module, disk module or infection of an !Boot.
