Is "Spyware" Watching You?
By Jim Edwards
Imagine my surprise when I received a phone call from a friend who told me
he'd been the victim of a "spyware" attack that left him shaking at his loss
I listened to his horror story with a sympathetic ear, but I felt secure
since I carry anti-virus software and a firewall (both by Norton).
At his suggestion - and to my surprise - I ran a program called "Spy
Sweeper" and found a veritable minefield of dangerous and harmful programs
lurking on my computer.
"Spyware" is software that gets onto your computer and
literally "spies" on your activities.
The spying can range from relatively harmless use of
cookies tracking you across multiple websites... to
extremely dangerous "keystroke loggers" which record
passwords, credit cards, and other personal data. That data then gets
relayed to the person who put the software on your computer.
Three primary types of spyware exist to complicate your online life,
3. malicious programs like "keystroke loggers"
Cookies represent mostly a danger of lost privacy.
In theory, someone could use a "cookie" to track you across multiple sites,
combine that data with several databases, and figure out a lot more
information about you than would make you comfortable.
"Adware" tracks more than just your movement across sites, it spies on your
installed software and computer habits to then serve up advertising, modify
websites before you see them, and generally do things without your knowledge
with the intention of trying to get you to buy things.
"Keystroke loggers" and other malicious programs exist for one purpose: to
cause personal mayhem and financial damage.
Spyware gets on your computer in one of several different ways.
First, it rides along with software you download from the 'Net and install
on your system.
Second, they come as email attachments (much like viruses) and automatically
install themselves on your computer when you open the email message.
Third, hackers find an open port on your computer and use the "back door" to
install basically anything they want.
And fourth, the more malicious types, like keystroke
loggers, can even get installed by someone with direct
physical access to your computer such as an employer,
suspicious spouse, business competitor, or someone who wants to know exactly
what you're doing.
Now, suppose you carry an up-to-date anti-virus program and a firewall -
shouldn't that represent potent protection?
In a word: NO!
I can personally attest that even the most up-to-date anti-
virus programs and firewalls will not (repeat, WILL NOT)
catch all the spyware that can infest your computer.
You need a program that specifically scans your system for
the tens-of-thousands of existing spyware programs along
with the new ones appearing daily.
Check out "Spy Sweeper" from webroot.com - this is the
program I used to discover the spyware on my computer.
One thing I noticed, however, is that this program is a
memory hog, so once I scanned, I turned it off and then
use it 2-3 times a week... not the best strategy, but
I want to give you the "whole" picture.
I also got the following recommendations from numerous
subscribers about 2 programs to specifically help identify
and remove spyware from your system (PC):
1. "Ad Aware" from lavasoft.de
2. "Spybot Search & Destroy" from safer-networking.org
The overwhelmingly recommended firewall suggested by readers
was Zone Alarm Pro from Zone Labs
The bottom line seems pretty simple (but lengthy) if you
want to protect yourself against this growing threat.
~ Keep your anti-virus program current
~ Install a firewall
~ Carefully screen software before installing it
~ Scan for specifically for spyware weekly
~ Stay current on this growing threat.
