- Permission is granted to copy this
- program along with it's documentation
- as long as such copying is not for
- profit.
-
- Getting started
- ---------------
- After executing the file
- VIRUSKIL.PRG you "should" be presented
- with several icons for you to "click"
- on.
-
- Icons
- -----
- These icons are as follows:-
-
-
- A B
-
- Examine Install
-
- Remove Exit
-
-
- Drive icons
- -----------
-
- The A and B are the drives A and B
- respectively. These determine which
- floppy drive the virus killer will
- operate on. If you only have one drive
- then you will not be able to select the
- drive B icon.
-
- Examine
- -------
-
- Clicking on the Examine icon will cause
- the virus killer to produce information
- about the disk in the current drive.
- This information is:-
-
- Executable, possible virus.
-
- The boot sector is executable.
- ie the program on this boot sector
- will be executed, if the ST is booted
- up with this disk in. On a standard
- disk this should, of course, not be the
- case. If you, yourself, have not put
- this program onto the boot sector then
- this may be a virus, and if this is so
- should be done away with. However, some
- commercial disks (particularly games)
- may have a short "boot" program (now
- you see why it's called a boot sector)
- to load in the program/game. If you
- remove a commercial disk's boot sector
- then you will, more than likely, not
- be able to use that particular program
- again. Unfortunately it is not possible
- for a piece of software, such as this,
- to tell a virus from a "genuine" boot
- program, so you must execise your
- judgement when it comes to getting
- rid of such boot sector programs.
- NB The authors can accept no
- responsibility for disks "damaged" in
- this way or any other data loss
- resulting in the use of this program.
-
- Boot sector not executable
-
- This means the boot sector
- will not execute on boot up and you
- have nothing to worry about.
-
- Anti virus installed
-
- This means an anti-virus
- (produced by this program) has been
- placed onto this disk's boot sector.
-
- Install
- -------
-
- This option will install an
- anti-virus program onto your disk's
- boot sector. On boot up this program
- will simply display the message
- "virus free disk" on your screen, so
- that you know that this particular disk
- hasn't got a virus on it. If a disk
- with an anti-virus installed comes into
- contact with a virus, the virus will
- write itself over the anti-virus. Then
- the next time you boot up with that
- disk you won't get the "virus free"
- message, because the anti-virus program
- has been written over by the virus
- program. So, on boot up, if you are
- expecting the message and you don't get
- it, you immediately know that a virus
- has written itself onto that disk. You
- can then get rid of it before it
- spreads and of course examine your
- other disks for the source of this
- virus. Also on monochrome systems the
- anti-virus will reverse the screen to
- produce white characters on a black
- background, when the desktop appears.
- Technical info....
- In no way does the anti-virus
- "wedge" itself into memory as would
- a virus. It simply executes on boot up
- and is then forgotten about.
-
- Remove
- ------
- If you don't wish to have an
- anti-virus on your disk, but just
- want to get rid of the virus, then the
- remove option will simply, remove any
- program that may be present on a boot
- sector (including viruses and game boot
- programs!)
-
- Exit
- ----
- This option will return you
- to the desktop. (Or to the calling
- program, if you want to be perdantic)
