Virus Memory Kill V12.0 by Chris Hames.

 (REMEMBER! no virus can copy itself to a write-protected disk.)

 This utility is perfect to put in the startup-sequences of your important
 disks being only 1992 bytes. It will detect and kill the viruses listed and
 then give an option to cold reset to be sure. You will know when you have an
 outbreak of a virus and can then disinfect your disks with an appropriate
 disk virus killer.

 But the best feature of this program is its ability to detect new viruses.
 It will detect all new viruses that stay resident(survive reboot) because it
 checks if CoolCapture, ColdCapture, WarmCapture or the KickTagPtr is not ze-
 ro. It also checks the jump addresses of routines commonly used by viruses
 DoIO, TrackDiskDoIO, VerticalBlank, SumKickData, AddTask, RemTask and the
 OldOpenLibrary routines.  When VMK finds that any of the above are abnormal
 it alerts you telling you what is not normal, gives you the value that is
 not normal and displays the memory around the location, which is indicated
 by a $ on left hand side of the actual location. You can look for text indi-
 cating what is causing the problem in the memory display. eg:
 "ByteBimboVirus".

 You then have an option of reseting it to the normal value or doing nothing.
 After all abnormal values are displayed you will be given a final option to
 cold reset to make sure.

 This program only works with the standard 1.2 and 1.3 versions of kickstart.
 It recognizes the programs ResNFM, Guardian V1.2, DiskManager, SystemZ
 V3&4(V4&5 BootBlock) and FaccII and will not alert you if it is them chang-
 ing one of the checked values. If you do not want VMK to check the KickTag-
 Ptr type "VMK t".

 This program may be copied for any purpose as long as it is unaltered and
 accompanied by this doc file unaltered. I take no responsibility for any
 problems that occur using this program. It performed fine when tested.

 Viruses Known by this Version

Microsystems
 Infects inserted disks. Eventually puts up screen "...MICROSYSTEMS". Look
 for "MICROSYSTEMS" in boot block.

DiskDok
 Infects inserted disks. Eventually starts formatting every 5th disk
 inserted from block 880. Look for "Disk-Dok" in boot block.

LamerExterminator
 Infects disks inserted. When in memory will return a normal boot block
 when it is actually the virus. Writes random blocks filled with "Lamer!".
 Boot block changes each time.

ByteBandit
 Infects bootable disks inserted. Starts interrupt that will blank screen
 after certain time. To recover:- Press these keys in order and keep hold-
 ing down as you press the others. Left-Alt, Left-Amiga, Space, Right-Amiga,
 Right-Alt. Look for "Byte Bandit" in boot block.

ByteWarrior(DASA)
 Infects inserted disks. Plays tune and flashes power led if Cool or Cold
 Capture are not zero at boot(eg detects SCA). Jumps straight into ROM,
 Guru's with Kickstart 1.0 1.1 & 1.3. Look for "DASA" in boot block.

SCA
 Infects booted disks that don't have $37fcbb02 CheckSum. Every 16th recre-
 ation, message appears "Something wonderful...". At reboot holding down
 left button will cause the screen to go green if it was in memory. Look for
 "Something won.." in boot block.

HCS4220
 Infects disks booted off. Starts interrupt power led flashs with drive
 step and also every sec. So called detector.

NorthStar
 Infects disks booted of that have $43fa0012 at $12 in bootblock (normal
 bootblocks). Look for "NorthStar" in boot block. So called Detector.

Obelisk
 Infects only if you have no fast ram and only disks you boot off that have
 $4eaeffa0(jsr FindResident(a6)) which cuts out most non dos loader disks.
 Puts up screen when booting "Obelisk..".

Pentagon (I want a copy)
 Detector.

Revenge	(I want a copy)
 Changes pointer to a male part of the body a minute after boot up.
 Kill/detect by pressing button on joystick in port 2 at reboot screen will
 go red.

IRQ (I want a copy)
 NOT A BOOTBLOCK VIRUS. Attaches itself to the first file in startup-sequence
 or c:dir. Every disk that is inserted that is write protected will cause a
 requestor("Volume is write protected"). Changes window to "...IRQ virus".
