COMPUTER
VIRUSES
HOW TO AVOID INFECTION
In a perfect world there would not exist the
continual manufacture of tools of destruction.
Unfortunately, the human condition is such that
there will always be those among us who will
maliciously set out to destroy the livelihood and
property of others. Just what kind of
satisfaction the propogators of computer viruses
gain from their odious efforts we may never know,
but the results are well known and well
documented.
I can offer three pieces of
good advice on this topic. Firstly, install anti-virus
software on your computer, and keep it regularly
updated. For those who can't afford the likes of
market leaders McAfee or Norton's anti-viral
software packages, there are plenty of other FREE
ANTI-VIRUS PROGRAMMES
available on the web.
Secondly, be careful with whom
you share floppy disks. These are a very common
method of virus transfer. Scan disks before
accessing them.
Thirdly, beware of email
attachments, in particular .exe files. Many a
virus has arrived on a computer via email. In
most cases these take the form of an .exe file
accompanied by a message that encourages the
recipient to open the file. Usually the file
appears to do nothing at all when clicked upon.
In most cases people would simply shrug and
concede that the file was faulty, then removing
it and not giving the matter another thought.
However, the execution of the file has already
been effected, and the virus is now on the system.
NEVER open an .exe file, even from a trusted
friend, unless you know exactly what it is,
without scanning it first.
It should also be pointed out
that Word and Excel files can carry viruses (usually
called "macro viruses") and should also
be scanned before opening.
Almost as insidious is the
spread of FAKE
VIRUSES. These are a constant
problem, because the main effect they have is to
cause congestion on the internet. These are sent
usually via email, and novice computer users,
panic-stricken by the information contained,
usually end up forwarding the "Bogus Virus"
information on to every person listed in their
address book.
These are, thankfully, fairly
easy to spot. Invariably they arrive with an
Urgent-looking UPPER CASE subject,
aiming to grab your attention immediately. They
then go on to suggest that "this is a new
virus and very few people know of its existence",
imploring you to "forward this information
to as many people as you can".
Other, perhaps more
laughable variations on the good old chain
letter, another type of email hoax, advise the
recipient of special offers by major corporations
such as Microsoft or Honda, or play on your
sympathy for some poor (non-existent) child dying
of aids in some far-off hospital, resulting in
millions of unwanted emails arriving at one
address and crippling the server in the process.
Don't be fooled by such
nonsense - consign this sort of rubbish to your
TRASH folder.
