March 16 2005:Spies In Your Computer, and How To Surf The Net In Safety
Hi there, and welcome to the latest Tech Talk bulletin
from the CallTheWatsons.com webmaster.
I get a lot of calls from friends
and family about their computer having one of three common problems:
(a)
Running slow
(b) Taking forever to boot-up
(c) Doing other odd things
it
shouldn't do.
In response to these calls I usually suggest that their
computer may have had SPYWARE installed, and then proceed to tell them how to
remove it.
You have probably heard of Spyware now. Either from friends
and family who have become victims, on the Internet, or even on TV ads for
Internet Service Providers like Earthlink, promising you Spyware removers etc.
But what is it?
WHAT IS SPYWARE? AND HOW DID IT GET ON MY
COMPUTER?!
Spyware is basically any program that is
installed onto your
computer in order to monitor your activity while on-line. Why would anyone want
to do that? Well, information is power, and so the more information people can
find about the sites you visit on the internet, or the time you visit them
etc.,
the more it helps organizations to better target marketing and even spam to
improve their sales.
"But how did the Spyware get on my computer in the
first place?" many people ask me. By visiting sites on the internet, often
sites
of a "dubious" nature, you are at risk of having these websites install
software
onto your computer through security loopholes in Internet Explorer, all
silently, without you knowing about it.
Not all Spyware is bad, or
installed on your computer unknowingly, however. The Google and Alexa
(Amazon.com) toolbars, for instance, are installed by you at your choosing, and
record your online habits for their own, legitimate statistical
purposes.
HOW DO I REMOVE SPYWARE?
To remove
spyware, your first
line of attack is to check your "Currently Installed Programs" list, which can
be found by going to the "Start Menu" > "Control Panel" > "Add/Remove
Programs". Look on there for any programs that look suspicious or unfamiliar to
you. Be sure that they are not legitimate programs before you remove them,
unless you want to go to the trouble of reinstalling them later.
You
might also check your "Start-Up" folder ("Start Menu" > "All Programs" >
"Start-Up") and see if there are any programs there starting up on system boot
that seem unfamiliar.
Most spyware, however, does not show up in the
Currently Installed Programs list or Start-Up folder, and is buried secretly
within the Windows Registry (a large system file that keeps track of all your
programs and system configuration information). Looking at or editing this
registry is beyond all but a handful of very knowledgeable
users.
Therefore, one must look to a smart program that can find the
spyware hidden in the registry. I recommend a number of programs for this. The
first two are FREE to use! They are:
1. AdAware Personal Edition
2. Spybot Search And Destroy
However, the most
thorough program on the the market right now is Webroot's SpySweeper -
http://spysweeper.com/, which according to PC Magazine, is able to rid a system
of 95% of current spyware. It costs $30 - worth it if you can keep your system
clean.
Because no single anti-spyware program can find all spyware
signatures (characteristic markers left by spyware) on your computer, it's
important to run several programs when trying to rid your system of spyware.
Microsoft are also getting in on the act,
however their anti-spyware is still at the early stages, and they have stated
that their solution is not intended to replace commercial anti-spyware, but is
just there as a supporting tool.
Follow the instructions on scanning
and
removing the spyware from your system with each program. You will have to make
some decisions on what to
remove, as each program will find both legitimate
and illegitimate spyware on your system. If you're desperate, just select
everything to remove, but be prepared to re-install things later on, if they
happened to remove a utility you were using legitimately.
If, after
running both these programs, your computer is still slower than it used to be,
or exhibiting other strange behavior. You may have to try another spyware
removal program, or check for viruses (I'm assuming that you ALL have a decent
anti-virus program installed!)
You should also look in your "System
Tray" (the bottom right corner of your Windows screen next to the clock). If
you
have a lot of clutter in the system tray, this could well be slowing down your
PC, as these programs automatically load on start up and stay loaded at all
times. Consider
uninstalling some of these programs using the "Add/Remove
Programs" tool I discussed above if you can do without them.
HOW DO I
PREVENT SPYWARE GETTING ONTO MY
COMPUTER IN THE FUTURE?
Nearly all
spyware finds its way into your computer through Internet Explorer, which is
famous for all the security loopholes people keep finding
in it. If you like
Internet Explorer, it's important to make sure you have the latest security
patches (updates that patch holes in Windows and Internet Explorer security)
downloaded from Microsoft.
At the very least you MUST ensure that you
have Windows XP Service Pack 2 installed. This was the most significant step
forward in tightening up your computer's security since the launch of Windows
XP
some years ago.
Go to "Start Menu" > "All Programs" > "Windows
Update" to make sure you have Service Pack 2 and all the latest patches. Even
better, set up your Windows to automatically check and download the latest
patches as and when they become available by right clicking on the "My
Computer"
icon in the start-menu, selecting the "Properties" tab and then selecting the
"Automatic Updates" tab. From there you can set the automatic update
choice.
An alternative is to use a different web browser. Many users,
frustrated with the continual security problems found with Internet Explorer
have
switched to the FIREFOX browser, produced by Mozilla. Statistics show
that usage of the browser has been growing at an explosive rate since its
launch
mid last year, a testament to it's usability and safety.
You can
download
the FireFox browser for free here.
Happy (and Safe!)
Surfing!
