THE SCA VIRUS: --------------------- The original. The one that
|
|
started all this craziness. It hids in memory, attaching itself to
|
|
ANY disk you boot off of.Prints the infamous "Something wonderful has
|
|
happened...",etc., etc. Install all disks that have it and then
|
|
reboot from a cold start or from a warm start HOLDING down the LEFT
|
|
miuse button.This puts it to death.
|
|
|
|
BYTE BANDIT VIRUS: --------------------- What the Byte Bandit virus
|
|
does is once it's in memory, it copies itself to just above the high
|
|
memory pointer on the first hunk of RAM it can find (Which means it's
|
|
not always in the same place), wedges itself into the Interrupt Server
|
|
chain, into the Trackdisk.device's vectors,and creates itself a
|
|
Resident structure so it can hang around after reboot. It watches
|
|
EVERY disk inserted, and will write itself to ANY bootable disk that
|
|
is inserted! This one can spread like wildfire - every disk you
|
|
insert into your external drive during a session with this Virus
|
|
loaded will result in all those disks being infected. Ouch. Also, if
|
|
you Install a disk while this virus is going, it will just copy itself
|
|
back to the disk - which is why it has to be wiped from memory to be
|
|
destroyed.
|
|
|
|
The REVENGE VIRUS: ---------------------- This virus is not yet
|
|
common in North America (I think Steve Tibbett is the first person
|
|
here to have a copy of it), but it is apparently making the rounds in
|
|
Sweden and Germany.What this virus does, is everything that the Byte
|
|
Bandit virus does,PLUS, after infecting a disk, it will wait one
|
|
minute after every reboot, and change your mouse pointer into an image
|
|
of a certain part of the Male anatomy. 8-) I think the reason this
|
|
virus is called the "Revenge" virus is because it looks specifically
|
|
for the Byte Bandit and for the SCA Virus. If it finds either of
|
|
these, it Rigs THAT virus so that it will CRASH the machine unless
|
|
THIS virus is loaded first. Note that I might be wrong about this -
|
|
that's the way it looks from the disassembly,- but be warned,in case
|
|
it pops up later or something. He stays in RAM via changing the
|
|
CoolCapture vector to point to his own code. He then intercepts the
|
|
DoIO() call and watches for any attempts to rewrite or to read the
|
|
boot block and acts accordingly.He also has an interrupt around
|
|
counting VBlanks until it's time to bring up his sicko pointer. To
|
|
get this virus out of memory is Simple - Hold down the Joystick button
|
|
(Plug a joystick into port 2, and hold down the button while you are
|
|
rebooting), and the screen will briefly turn RED during the boot, and
|
|
it's out of memory. (If you hold down Joystick button AND mouse
|
|
button, it will half-remove himself from RAM and turn the screen
|
|
Blue).
|
|
|
|
THE BYTE WARRIOR VIRUS: ------------------------- The Byte Warrior
|
|
Virus is a lot like the Byte Bandit virus, except it is not designed
|
|
to hurt anything - it will start an "Alarm" sound if it sees another
|
|
virus (or at least I think it does - it hasn't for me), but other than
|
|
that, it will write itself to any disk inserted. There is also a
|
|
hidden message in it, asking us to spread it around and not to erase
|
|
it. Ya, right.
|
|
|
|
THE NORTH STAR AntiVIRUS: -------------------------- This virus
|
|
alerts you to the presence of other viruses.I think this sort of idea
|
|
is stupid because it can do just as much damage as the rest of them.
|
|
|
|
THE OBELISK SOFTWARE CREW VIRUS: THE PENTAGON CIRCLE VIRUS: THE
|
|
SYSTEMZ VIRUS: ---------------------------------- More of the same.
|
|
|
|
THE IRQ VIRUS: ------------------------- The FIRST non boot-block
|
|
virus! This one is murder! Since it does not attach itself to the
|
|
boot block it is not a simple think to find. This baby attacks the
|
|
FIRST executable file in your startup-sequence or,if it can't get at
|
|
that file, it will attack the DIR command in your C directory! Get
|
|
and read the fine writeup of this virus by S.Tibbett included with his
|
|
VIRUSX utility.
|
|
|
|
Anyway....the saga continues......
|
|
I highly recommend that you get a copy of Steve Tibbett's excellent
|
|
utility, VIRUSX (the current version as of 9/16/89 is VIRUSX3.20 ).
|
|
This fine utility detects all 16 known viruses and kills them on the
|
|
disk and in RAM. The built-in sector-viewer allows you to see the
|
|
virus on the disk and to also observe any unusual boot block code.
