viruses are computer programs written by people whose intent (for
whatever reason) is to cause problems on your computer system. The
effect of computer viruses varies enormously - some simply display
an irritating message every time you start the computer while others
will erase or corrupt data on your computers hard disk.
Viruses have
a "self-replicating" feature which means that they can
be passed from one computer to another - sometimes via floppy disks
but more commonly now via the Internet. You can protect your computer
against viruses by installing and using Virus Checking software
which can detect the presence of and remove viruses.
Computer viruses
are actually less common that you might think, given the
media coverage that they receive. If your computer exhibits a problem
it is very easy to jump to the conclusion that it has a virus but
frequently this is not the case. Most problems are caused by bugs
or incompatibilities in software, poor system configuration, or
hardware breakdown.
Some simple
rules can minimize the risk of virus attack
on your computer -
Install and
use professional Virus Checking Software.
Ensure that you configure this software to protect your e-mail
system.
Keep your
Virus Checker up to date.
This usually means paying and annual licence fee and downloading
the latest virus software from a website on a regular basis. This
is very important. New viruses appear all the time - out of
data virus checking software is worse then useless because it
makes you think you are protected when you are not.
Be very suspicious
of unsolicited e-mail. If
you don't recognize the sender's address or are at all suspicious
of the e-mail content then do not open the e-mail - delete it
without reading.
Be very suspicious
of e-mails which have attachments
which the e-mail actually suggests you should open (e.g. "Open
the attachment to have a laugh..."). Also be wary of e-mails
which use CAPITAL LETTERS to describe everything.
Always run
"Virus Checking" software
on any floppy disks received from outside.
If you suspect
that your computer has become infected by a virus proceed as follows
-
Don't panic
!
Verify that
the problem is caused by a virus and not some other software problem.
If the problem only affects one program then it is more likely
to be a problem with that program rather than a virus
Do not send
any e-mail, create any floppy disks or CD-ROMs until the problem
is solved, or any virus my be transferred to another system or
the diskette/CD to re-infect your computer again later,
Run your
virus checking software and scan your system for viruses
Any good virus
checking software will have full instructions on how to detect and
remove viruses from your system. For more information on viruses
