BEWARE
OF FREEWARE! THEY CAN JEOPARDIZE YOUR SYSTEM OVERALL
SECURITY
-
Questions: What that's again? Beware of freeware?
And what else? Now! Are you hinting that one should
avoid using freeware?
- Replies: No that is not my intention.
I just want to draw your attention to the fact
that some freeware may be just SPYWARE.
And furthermore they may be a threat to the
overall security of your computer. They can "create"
security holes by keeping your computer's ports
opened to vicious attacks by all sorts of malicious
viruses and Trojan horses.
HOW CAN THAT
BE?
That's the right one. How can that be?
From time to time, I used to fire up WINDOWS
COMMANDER to scrutinize and remove redundant
files / folders from my system in partition C:\Windows\*.*.
Files and folders in the TEMP directories particularly.
One day I was astonished and baffled to remark
files (.exe) I did not at all remembered downloading
and installing and some peculiar folders. I was
really puzzled. Where did they come from. And
then, surfing the Web, I came across a small
utility / freeware which claims that its role
is to identify spyware. I made some search
about spyware.
WHAT IS A SPYWARE?
A spyware - also known as "adware" - is a hidden
software program nested deeply inside a system
which transmits user information, via the Internet,
to advertisers.
Spyware are introduced - as Trojan Horses by some
Freeware programs - into your system without you
knowing anything about the introduction. That's
the way some Freeware programmers pay themselves
back selling your surfing behaviors and "tastes"
to advertisers - in addition to the "legal"
advertisement banners you freely accepted with the
freeware when you punch the "Accept" button
of the "Disclaimer". They made it
true the popular saying: "There is no such
thing as free meal"
These Freeware / spyware combination store your
personal information somewhere on your hard drive,
and routinely transfer these data via the Internet
back to advertisers in exchange for more advertising.
Now I am sure that you've got it and see clearly
why you should beware of freeware!
USING ADD / REMOVE TO GET
RID OF SPYWARE IS NOT ENOUGH
So you decide to kill the plot and use Windows Control
Panel's Add / Remove to cleanup your system from
all these nested Trojan Horses? Poor of you. Windows
Add / Remove is useless. Yes useless against the
"snakes". The spyware will remain on
your computer; often buried deeply within the Windows
System Registry or nested into a hidden / secret
folder bearing a simple cookie! Yes Spyware's
creators are resourceful.
HOW TO REMOVE SPYWARE?
Detecting and deleting spyware requires additional
software.
Fortunately there is always a savior around. Just
search and you shall find. You have many options
at your disposal:
-
1- The simple solution
of checking a freeware to be sure that it
is not hiding a spyware before download
and installing it. Many utilities are available.
I use a freeware called SPY CHASER
by Camtech available here.
It features a database of more than 700
freeware / spyware.
However this is a static solution. What
about the spyware already nested inside
your system and performing their dirty job?
-
2 -There come in a more
sophisticated alternative which cleanse
all "the beasts" from your harddrive
and the registry.
A free, non-advertiser sponsored product
called OPTtOut here
available from Gibson Research Corporation,
will identify several programs considered
to be spyware. OPTOut scans your hard drive
and give you the opportunity to remove spyware
or monitor their activities in and out your
system.
I personally use the utility from lavasoft.de
called Ad-AWARE. The first time I
installed it and performed the scanning
of my computer I was amazed to find out
that 19 spyware were nicely nested - 10
being comfortably "seated" inside
the Registry with adequate Registry's keys!
However, this alternative of cleansing
all the "beasts" from your hard
drive and or the Registry is not a radical
solution either.
As your data had been already transferred,
the "spy agencies" out there on
the Internet will keep on sending cookies.
These cookies may find their way easily
into your system when you are surfing. Even
if you have a firewall
installed. And you will need to do the cleansing
often and often.
-
3- The sentinel alternative:
an utility which stands as a guardian and
doing a permanent screening job over the
several ports of your computer. It stops
non-authorized "leaves" and send
incoming intruders packing back to their
sources.
I use AD-WARE + from lavasoft.de
which features a small add on to the free
version of AD-AWARE. It is called AD-WATCH.
Ad-watch is a vigilant which makes it sure
that any "bad" cookie which sneaks
its way into your system is automatically
removed. And to make sure that I remain
the absolute regent of my kingdom I added
ZONEALARM
ZoneAlarm is a freeware, non-spyware, non-advertiser
sponsored product. It monitors all Internet
traffics in and out your computer. Depending
on the configuration you opt for, it is
capable of stopping any unauthorized transmission
of data leaving your computer; and blocking
any "ping" or other outside malicious
attacks engineered by hackers. Click
here to get it.
TAKE MEASURES
TO PROTECT YOUR SYSTEM
If you are concerned about the
security of your system (not to speak of the confidentiality
of your surfing habits), you should install these
useful tools above described in order to avoid
troubles.
Since I have them installed, my firewall
- ZoneAlarm - performs more efficiently.
Trojan horses introduced by spyware can do a lot
of damage to your system. Even if most of spyware
do not intrinsically represent a serious threat
to your system, some of them can act as "Gate
Opener" for more dreadful Computer
worms, Viruses and powerful
Trojan horses.
These dreadful "beasts" will enter your
system more easily through ports kept opened by
the spyware and perform havoc on your machine.
They can scramble information on your computer's
hard drive, e-mail threats and confidential information
to every one listed in your mail system's Address
Book, or scan your computer system for credit-card
numbers and other kinds of financial information.
HOWEVER
Be advised that removing a spyware may sometimes
destroy the related freeware's performance. The
freeware may stop performing its "normal"
job.
The choice is yours. Security and Confidentiality
or Free Meal?

KNOW YOUR SYSTEM. USE
A POWERFUL SYSTEM ANALYZER
Sound odd? Of course that
you do know your system through the brochures
and documentation given to you when you purchased
it.
Furthermore with 1- Start 2-Settings
3-Control Panel 4- System and 6-
Devices Manager you can have more information
about all the components of your working tool.
YOU
CAN GET INTO TROUBLE WHEN YOU UPGRADE
Yes. But what about upgrading the Operation System
from Windows 95 to Windows 98 for instance on
a bargain computer (which
lack the precious documentation)
and finding yourself with a monitor displaying
only a meager choice of 2 to 16 colors (yes!
two to sixteen colors' choice only). A monitor
screen with blotted gray and miscellaneous awful
colors?
I
can testify that that occurrence is a possibility
when upgrading from Windows 95 to Windows 98 on
a computer without documentation.
After performing the upgrade, the Start strings'
sequence above mentioned may give you a vague
description of the Display Adapters: Standard
PCI Graphics Card.
What do you do then? How do you recover the striking
full True Color that your monitor was displaying
under Windows 95? If you 1 -Fire up the
System logo in the Control Panel 2- Highlight
the Monitor logo 3 - Choose Properties
4- Hit Drivers and finally 5- Punch
Update Drivers, Windows 98 will show a message
that "the best drivers had already been
installed" for the identified Standard
PCI Graphics Card.
So if you rely only on Windows 98 to troubleshoot
the Monitor awful color
display, you are stuck!
Even if the above mentioned example won't happen
to you (why bother with a bargain computer...)
you may need to tweak with your System.ini
or any other system files to fine tune your computer
for PC-to-PC or PC-to-Phone communication for
example. And unless you have a perfect practice
of the DOS Command Line (which means that you
are the generation before Windows 3.1 and the
like) you cannot easily find the system.ini and
system.bat Etc.
YOU NEED A POWERFUL SYSTEM
ANALYZER
All that to bring to your attention that, one
way or another, you need to have an intrinsic
knowledge of of your computer.
You cannot rely only on the diagnosis tools
available through the Control Panel. They
may prove insufficient when you are in trouble
and searching for solutions.
In order to save time, to avoid headaches and
fine tune your system when you do need it, it
is highly advisable to install a third party Diagnosis
tool.
A good third party diagnosis tool should be
able to display the trade marks of all the components
of your system and other useful characteristics.
Knowing trade marks of components will help you
troubleshoot your system when you need it. With
the third party system analyzer I installed I
succeeded in resolving very quickly the Display
Adapter's enigma. The Standard
PCI Graphics Card turns out
to be a good performer Matrox Millenium II.
I got its Windows 98 drivers from the manufacturer'
site and that is: the monitor
is now displaying brilliant and striking
True Color with several choices of resolutions.
PLENTY OF DIAGNOSIS TOOLS
ARE AVAILABLE
There
are plenty of diagnosis tools available over the
Internet.
The best one is SISOFT SANDRA - A system
analyzer combined with a powerful diagnostic and
reporting Assistant.
SANDRA provides a set of tools for diagnostic,
benchmarking, and performance tune-ups for different
hardware devices and subsystems of your computer.
The FREE version is already a must have.
