DETAILED INSTRUCTIONS FOR USING !VZAP
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
INSTRUCTIONS
~~~~~~~~~~~~
!VZap is quite self-explanatory and easy to use. It also supports Acorn's
interactive help application.
However, there now follows a brief run down of it's usage and various options.
In addition, full support is provided for Acorn's Interactive !Help application.
Before using !VZap, it is best to make a backup copy and store this safe
somewhere in case you should need to re-install it.
MAIN MENU: (obtained by pressing MENU, the middle mouse button, from the icon bar)
~~~~~~~~~~
Info Gives information and version number.
Kill Task Allows access to a sub-menu containing up to the last ten
tasks loaded. Clicking on a specific task will 'Quit' it.
This is handy, especially if unknown 'suspicious looking'
tasks suddenly load for no apparent reason.
Choices... Opens the 'Choices' window (details below)
Quit Quit !VZap and remove from the icon bar.
THE CHOICES WINDOW:
~~~~~~~~~~~~~~~~~~~
For ease of use, only half of the choices window is visible when you select this
option from the main menu. To toggle full size, click SELECT on the top right
(toggle size) icon on the window pane.
Initially, the following options are available:
AutoScan:
---------
Scan floppies If on, !VZap will automatically scan floppy discs for
viruses as soon as you click upon the drive icon on the
icon bar. After you've scanned all your floppies, which
may become a bit tedious, hence the ability to turn it on
and off.
N.B. This facility will temporarily override the 'AutoZap'
feature and turn it ON, irrespective of it's normal setting.
It will return to it's previous value as soon as the scan
has been completed.
On startup: Entering a directory filepath into the blank box will tell
!VZap to automatically scan any specified directory next time
!VZap is loaded (assuming you save the options - see below).
You must specify the FULL pathname of the directory you wish
to scan. ie. entering
ADFS::HardDisc4.$.Applicats
will scan the directory called 'Applicats' in the root
directory of HardDisc4.
N.B. You can drag a specific directory into the choices window
in order to save typing the full filepath, if required.
To cancel, simply ensure that this icon is empty.
Virus Scan:
-----------
Wimp watch If on, !VZap will bleep each time a new task or application
loads, and will also keep an eye on the wimp environment,
informing you of any changes or alterations that occur.
Autozap If on, !VZap will automatically deal with known viruses when
it is doing a disc scan. This is handy if you are a novice
user, or simply want viruses removed with no user
intervention.
HOWEVER. If this is on, ONLY VERIFIED viruses are dealt with.
If off, !VZap will pick up any files that simply 'look
suspicious' thereby possibly detecting any as yet
undiscovered viruses. It is best to keep this option on
unless you are aware of how to examine !Boot files using
!Edit.
(see also 'On startup' above)
*Set Again, this option is for the more technically minded and
allows a more thorough search of files.
This will pick up any attempts to *SET an alias and then
load a virus by calling the alias. It is inevitable that
when this option is on, many false alarms may be given.
Unless you know how to interpret !Boot files in detail,
then leave this option off.
N.B. If autozap is on, ONLY verified viruses will actually
be eliminated, so you don't need to worry about the
increased 'sensitivity' of this option, deleting important
files.
Stamp If on, !VZap will save a short text file to the disc just
scanned, informing future users that it is free from
viruses known to whichever version of !VZap you are using.
Auto Quit If on, !VZap will Quit automatically as soon as a virus
scan has been carried out. This can be useful if used in
conjunction with 'On startup' (described above) as it will
free the memory occupied by !VZap as soon as a virus scan
is complete.
NOTE: Should you wish to override this feature once it has
been set, hold the 'Q' key down when you load !VZap. This
will set it to 'off' but will NOT change the permanent
setting, saved on disc. To do this you will need to 'Save'
the choices again.
Logging:
--------
Disc log If on, !VZap will write a text file to disc containing
any relevant comments whilst it does it's virus scan.
The file is automatically created inside the directory
called DirLog, inside !VZap itself, and is called LogFile.
This option is especially useful when used in conjunction
with 'Autozap'.
Auto Reset If on, this will ensure that the log file is deleted each
time !VZap is loaded. This means that the log file only
contains information relevant to the scans you've carried
out during the present session. If the option is off, the
log file will simply be appended each time you run !VZap
so a continuous log may be kept. Obviously, depending
upon how many times you carry out a virus scan, this file
may become quite long.
Log path Contains the name of the log file. By default, it is called
"Logfile" and stored within the !VZap directory itself. This
file should not be deleted (even if the filename is moved
elsewhere) or !VZap will fail to install correctly. You can
drag the icon into a new directory window to set the full
filepath to a different directory. This option is saved with
the choices, so be careful if you move !VZap to another
computer.
N.B. Be careful if you decide to store the logfile within
!VZap itself, as VZap does it's own verification and will
not like more than a single (text) logfile within it's own
directory. If you change the filename from the default
"Logfile", ensure you delete any previous log files.
Activating Choices:
-------------------
Default Clicking on this icon will restore all the above options
to their preset 'factory' settings. Well, the ones I've
