What is ADWARE? |
[ Go
Back ] |
| |
Adware is program supported by advertisers that is installed onto a computer
system typically after a user downloads free software or web based services.
These types of programs may display banners or popup windows that while
being run reports Internet usage, behavior or habits to third-party
affiliates. The user gives permission to these marketing practices by
downloading the free software. It is not malicious by does drain computer
resources, causes longer boot ups and will degrade computer performance.

What is MALWARE? |
|
| |
Malware is a generic term used to describe unwanted software containing
viruses, Trojans, or any malicious active content that is designed to attack
an unprotected computer system. Malware can drain resources and cause
performance degradation or corrupt critical system files that will prevent
system boot up.

What is SPYWARE? |
|
| |
This is a generic term used to describe technology that assists in
collecting information about an end-users computer activity and Internet
usage. Unlike ADWARE, some web sites and commercial organizations will
install a SPYWARE application without warning or the user's knowledge.
The design of the SPYWARE application can be to collect information for
marketing research or to cause harm. All SPYWARE will use the
computer's resources causing performance degradation. There is alarm for
this practice because it costing companies thousands of dollars annually due
to production down time, repairs and maintenance. Furthermore, there
is a serious concern about invasion of privacy and using private information
for monetary gain without permission.

How does it happen? |
|
| |
As a general rule remember the old saying - "If it is too good to be true,
it probably is". Nothing is for free and most of the trouble begins by
downing free software or using free Internet based services eg: emoticons,
screen savers, date and weather watchers, web tools, free photos, music
downloads and search engine tool bars. Once a user downloads these programs
or subscribes to these services, additional software is installed to monitor
the user's activity and collect information to send back to advertisers. All
of these activities drains the computer's resources, prevents web browsing
or worse corrupts critical system files which ultimately could cause the
computer to be inoperable.
Intrusions can also occur when user receives and responds to a message or
e-mail to download some type of performance enhancing application for their
browser, memory, etc.. Typically these messages appear to be from legitimate
sources or a trusted zone, which can cause the novice end-user to believe it
is necessary or something they need to improve their computer experience.
Unfortunately, this is a deceptive practice by advertisers and Malware
developers to have access to the user's computer system and/or monitor
Internet activity.
Another venue employed to access end-user's
computer systems occurs when using a valid e-mail address to register for
newsletters, Internet shopping and bulleting boards. The e-mail addresses is
collected and harvested back out to marketing data warehouses that can then
determine IP addresses and begin sending SPAM and pop-ups.

How to safeguard against this
practice? |

Sometimes our Internet experience is improved
by the use of cookies. Therefore, totally eliminating Spyware is
unrealistic given many of them use cookies as a way to gain access to your
system. However, there are measures you can take to minimize the amount of
ad-ware on your system and prevent malware intrusions.
- DO NOT DOWNLOAD any applications
(freeware, shareware, or promotional/trialware) unless you are certain it
is spyware free and you have initiated the request.
- READ THE FINE PRINT. Read the End-User
License Agreement (EULA) thoroughly before installing an application. Most
users blindly accept this license without realizing they may be giving
their right to privacy away.
- Do not use your private or business e-mail
address for public Internet usage. To register for these services
create an Internet based account like Yahoo or Hotmail and use that as an
active e-mail account.
- When surfing the Internet and you are
asked to download Active X controls "DO NOT ACCEPT THEM". The warning
states it is necessary, but only accept it if know the source is valid.
Unfortunately, many of these providers are designing their pop-up windows
and request like legitimate sources. Thus, be very careful and when
in doubt, do not download.
- Know what you are getting. Make sure whatever
program you are planning on installing does not have extras that come with
the package. The major contributors are music downloads like Morpheus, Kazaa
and any
FREE downloads, screen savers, search utilities, and advertisers from Instant
Messaging applications. If you receive a pop-up window asking you to
vote on an issue, decline. Never click on a banner, false window alert
messages, any advertisement or ad search tool bars. If your default web
page mysteriously changes, you most likely have Spyware.
- Check the programs installed on your system.
If it looks suspicious, it probably is. If you are uncertain about a
program, you can do a quick search using Google, MSN, Yahoo or other known
search engines to find out if it is legitimate. Click here for a

- Install a software firewall like
Norton Internet Security
or
McAfee Personal Firewall
and keep the updates current.
There are also many good free programs available; however, be sure they
have the latest technology to prevent intrusions and provide restriction
controls.
- Keep your windows operating system critical updates
current.
