One of the saddest things in
the entire world is hearing the words, "I think
I've been hit by a virus" or "my computer was
destroyed by a virus, can you
help me please?"
Every time I hear these words I
want to cry - well, actually I want to scream in
frustration and a little bit of anger. You see, it's not
hard to protect your system from destruction by any one
of the fifty thousand or more viruses out in the wild. In
fact, it's so simple that it's pitiful that anyone gets
caught "with their pants down" more than once
in his or her lives.
By this time it's inconceivable that anyone with any contact
with
civilization is ignorant of viruses and their destructive
potential. A few
years ago you could claim ignorance (what's a virus?) but
no longer. In
these years after "I love you" and "Melissa",
well, virus attacks appear on
the 6 o'clock news at least once a week and in the newspaper
just as often.
That's one of the reasons why I groan when I hear that
someone has lost
their system to a virus attack. They cannot claim that they
didn't know or
didn't understand. In addition, protection is so simple
and cheap that no
one can use the excuse of "it's too expensive"
or "it's too difficult".
Sorry, that just does not hold water.
Look at it this way - if
someone is surfing the internet they must be paying for
a connection (say twenty dollars a month) and they have
to have a computer (perhaps a thousand dollars). It's hard
to accept that they cannot afford another thirty or fifty
bucks for virus protection (in fact, many new computers
come with an antivirus program pre-installed).
All right, preaching aside, what's the best way to protect
your system from
virus attacks? To begin with, assume that you or someone
who uses your
computer might make a mistake and plan for the worst. In
other words, make
the assumption that if a virus is received, it will be executed,
so make
sure the things are removed or rendered harmless before
you see them.
Define and follow a good backup
plan - First and foremost, figure out how you are
going to back up your data. Didn't expect me to say that,
did you? You have to understand that no virus protection
system is perfect. If a virus does get through somehow,
then you must be prepared to restore your data and files
from a backup.
It does not matter if you hand copy your critical files
to a floppy disk
every night or if you have the most advanced optical or
tape backup system
available. If nothing else, get a cheap ZIP drive plug it
in and use the
backup software that comes with it (you can get this setup
for around a
hundred bucks).
Don't even think twice about this
- if you don't have a backup solution then get one,
now. If you are not keeping a backup then you are living
on borrowed time (this also protects you from system failures,
hackers and other dangers as well). ALL good security plans
begin and end with the backup and restore strategy.

Choose, install and maintain an
antivirus solution - Personally, I really like the
Norton Antivirus program. I've installed it in our office
and in my home, and I have not yet found a better program
anywhere.
There is far more to an antivirus program than just checking
for viruses.
All of them do that. What Norton does that's different is
very important -
it also scans incoming emails for viruses so they are removed
even before
you open the message.

Schedule virus updates at least
once a week - More importantly, you can schedule
virus updates to occur at regular (weekly) intervals. This
is extremely important. Your virus definitions MUST BE UPDATED
AT LEAST ONCE A WEEK. Otherwise, your protection slowly
loses it's power to protect your system. This is almost
as bad as not having any protection at all - because you
think you are protected and you are not.
Scan your hard drive as often as
possible - Use your virus scanning program to scan
your hard drive for viruses on a regular basis. I've scheduled
mine to scan every night while I sleep (the computer is
not doing much else at that time, after all). This way any
viruses that do slip through your defenses should be caught.
If you run Outlook, then download and install the Outlook
Security patch
(unless for some reason you want to use email scripting,
which you probably
only need if you are a developer). This will prevent you
or anyone on your
computer from accidentally opening an attachment which is
actually a virus.

Install ZoneAlarm Pro - Not
only is ZoneAlarm Pro an excellent firewall, it is also
a virus scanner. It actually scans files as they arrive
on your system and tags suspected viruses with a special
file type. This will prevent you from accidentally opening
an email attachment that is a virus.

Subscribe to several newsletters about viruses - It's important
to become
aware of viruses and the associated problems and risks.
My recommendation is
to subscribe to the following newsletters. They are all
free and even a
quick glance at each one will help you become more aware
of what's going on.

Additional Information
Backing Up Your stuff - Part
1 http://www.internet-tips.net/System/backup00.htm Backup
may seem to be a pain, but it's one of the most important
things that you can do to protect your system.
Backing up your system is an essential part of your security
scheme
http://www.internet-tips.net/Security/Backups.htm
Backups are extremely critical to keep your system secure.
If your system is
damaged by a virus or an intruder you have a way to recover.
Remember,
however, that you must think through and test your scheme.
Outlook Security Patch
http://www.internet-tips.net/Security/Virusoutlooksecuritypatch.htm
If you run Outlook and you want to protect yourself, you
should install the Outlook security patch.
Products - Norton Antivirus
http://www.internet-tips.net/Products/nortonantivirus.htm
You need antivirus protection for your computer. Norton
Antivirus is by far and away the best solution for the desktop.
Products - ZoneAlarm Pro
http://www.internet-tips.net/Products/zonelarmpro.htm ZoneAlarm
Pro is quite possibly the best firewall product for personal
home use that currently exists. Highly recommended.
Viruses
http://www.internet-tips.net/Security/Viruses.htm
The most important thing you can do to protect your system
is install a
virus checker (also known as an anti-virus program). These
programs will
scan your system for viruses and Trojan horses and delete
or repair them.
There are several products including those by McAfee and
Norton (Symantec).
