All About Adware
In a previous article, titled All About Spyware, I detailed
exactly what spyware was, how it can harm you and your computer
and ways to avoid getting spyware on your computer. Now I want
to turn my attention to adware.
Many describe adware as the lesser of the two evils compared to
spyware. And for the most part, that is general true. However,
many forms of adware are just as destructive as spyware, and can
cause you a great deal of time and aggravation trying to get rid
of it.
Like my article on spyware, I want to start off by defining
exactly what spyware is. According to McAfee Inc., the leader in
spyware and adware protection solutions:
Adware is software whose primary function is to make revenue
through advertising that is targeted at the person using the
computer on which the adware is installed. This revenue can be
made by the vendor or partners of the vendor. This does not
imply that any personal information is captured or transmitted
as part of the software's functioning, though that is often the
case.
A better but much longer (and my personal favorite) definition
of adware comes from geekpatroloncall.com. They define adware as:
Adware, also known as an Adbot, can do a number of things from
profile your online surfing and spending habits to popping up
annoying ad windows as you surf. In some cases Adware has been
bundled (i.e. peer-to-peer file swapping products) with other
software without the user's knowledge or slipped in the fine
print of a EULA (End User License Agreement). Not all Adware is
bad, but often users are annoyed by adware's intrusive behavior.
Keep in mind that by removing Adware sometimes the program it
came bundled with for free may stop functioning. Some Adware,
dubbed a "BackDoor Santa" may not perform any activity other
then profile a user's surfing activity for study. AdWare can be
obnoxious in that it performs "drive-by downloads". Drive-by
downloads are accomplished by providing a misleading dialogue
box or other methods of stealth installation. Many times users
have no idea they have installed the application. Often Adware
makers make their application difficult to uninstall. A "EULA"
or End User License Agreement is the agreement you accept when
you click "OK" or "Continue" when you are installing software.
Many users never bother to read the EULA. It is imperative to
actually read this agreement before you install any software. No
matter how tedious the EULA, you should be able to find out the
intent BEFORE you install the software. If you have questions
about the EULA- e-mail the company and ask them for
clarification.
As you can see from these two definitions, adware is just as bad
as spyware.
I offered five great tips previously on how to protect you from
spyware. So here are five tips to protect your self from adware:
1. Buy a good, comprehensive software program that protects your
computer. For this, I have to recommend the products that I use.
I use McAfee Internet Security Suite and XoftSpy, which is a
malware scanner. These products can stop spyware and adware dead
in its tracks. If you already have adware or spyware on your
computer, these products can find it and delete it for good
(http://www.delete4good.com).
2. There is no such thing as a free lunch. When you download
freeware or shareware, chances are that you are downloading
adware with it. Many programmers will offer a "free" trial of
their software that you can use. However, adware is built into
the "free" program to bombard you with advertisements for the
"paid" version of the freeware that you are using.
3. Certain "types" of websites are notorious for adware. Those
"types" of websites include: peer-to-peer sites, free games
websites, and pornographic sites. If you frequent these type of
website, make sure your computer is protected (see number 1
above).
4. Make sure that your web-browser security settings are
configured correctly. This can prevent adware or other malicious
software from automatically downloading on your computer.
5. Never, never, never click on pop-up ads. I know that some
pop-up are irresistible. But they are irresistible for a reason.
Pop-ups are meant to get your attention. But if in the pursuit
of your attention, they get you to click on them, you may get
more than you bargain for.
The best thing to do is stop pop-ups from showing up on your
computer in the first place. Most web-browsers come with a
respectable pop-up blocker. If your pop-up blocker is doing a
poor job of blocking pop-ups, Yahoo and Google offer excellent
programs that work well. They're free and they come from a
reputable source.
Protecting your computer has turned into a multibillion-dollar
business. But, even the best spyware and adware protection is
useless if you don't take necessary precautions. Doing just a
little bit of research and taking a few precautions can greatly
reduce your risk of being exposed to spyware, adware, viruses,
trojans and other so called malware.
