Four-Step Defense Against Spyware and Parasites
By Marty R. Milette (c) 2005

Everyone knows about spyware, parasites and other malware.
I won't review them all here -- but what you may NOT know
about is a PROVEN, FOUR-STEP defense that will virtually
guarantee that your computer is protected in a practical,
simple manner.

Let me spoil the secret before you even read the article!

The steps are:

1. Install a good anti-virus program.

2. Install Spybot Search and Destroy.

3. Install Microsoft Anti-Spyware.

4. Keep everything up to date!

Can it really be that simple? YES!!!

How do I know? This is exactly what I have done to clean
and disinfect over 300 computers at two different companies
-- keeping them operating parasite-free for the past two
years! Here are the details...

1. Install a Good Anti-Virus Program.

If you are running any computer without a good anti-virus
program these days -- you're committing cyber-suicide!

It doesn't really matter which one you use. There is such
stiff competition between companies to keep up -- every one
is pretty much about the same -- or at least -- it will be
very quickly. So don't sweat it. Use ANY one you want
-- but just be sure to use one!

(I personally use McAfee, and receive virus-laden emails
every couple of days that are automatically deleted.)

2. Install Spybot Search and Destroy.

I don't generally recommend products, but make the exception
in this case because this program REALLY WORKS -- and is
FREE! (I DO encourage you to make a donation!)

Get it here: http://www.safer-networking.org/en/download/

Another tip: DO USE the "Tea Timer" continuous protection.
It is turned off by default -- so when you see the prompt
to enable it -- please do! It is much easier to PREVENT a
problem, than to try and cure it later.

3. Install Microsoft Anti-Spyware.

Many people believe that just because they have ONE
particular anti-spyware program, that they are covered.

DEFINITELY NOT! Spyware is one case where you absolutely MUST
use both a belt and suspenders.

You will find that there are many bits of malware that
Spybot S&D catches, but Microsoft doesn't -- and vice versa.

Also, one product may catch the parasite, but only the other
one can successfully remove it.

Microsoft Anti-Spyware is available here:

http://www.microsoft.com/athome/security/spyware/software/

If you have a LEGAL copy of Windows, the download is FREE!
(But be warned that they WILL CHECK your windows, and you must
download and install the checking too. No big worries.)

4. Keep Everything Up To Date!

Last, but certainly not least, you absolutely MUST keep
your operating system, anti-virus and anti-spyware products
updated.

Microsoft releases patches and updates to all currently
supported versions of Windows almost weekly. Use the
"Automatic Update" feature to make sure you get them, or
check manually at least once a week through Internet
Explorer's <Tools><Windows Update> menu option.

Don't forget about keeping the other products updated also.
In previous versions of Spybot Search and Destroy, you
needed to do this manually.

Removal and Cleaning

Ideally, these four steps should be done just after the
system is first set up and before it ever hits the
Internet -- but if this isn't the case, don't be surprised
at all the viruses, parasites and malware you may find.

If this is the case, my recommended removal and cleansing
method is a 'top-down' approach -- from the simplest and
safest method -- down to the more difficult and dangerous.

(Legal: Everything in this article is "At Your Own Risk".)

1. See if the application has a menu entry or an "Uninstall"
or "Remove" option anywhere. Most legitimate software (but
ones that may carry parasites as extra baggage) may be able
to be removed (at least partially) this way.

2. Under the Windows Control Panel, select the "Add/Remove
Programs" applet -- look for, and "Uninstall" anything that
may be related to the malware. Be aware that many "innocent
looking" applications carry spyware, malware and parasites.
Remove anything in any way resembling problems exposed
through either of the anti-spyware programs.

3. Use the removal features of the anti-virus and
anti-spyware applications. I recommend doing this AFTER the
previous two steps, because sometimes the applications will
be removed more 'cleanly' by reversing their original
installation process.

Note: After performing any step, be sure to repeat the scan
with the anti-virus and/or anti-spyware program to see if the
problem was really fixed. You should continue trying to
remove the problem until the scan comes up clean. This may
also mean rebooting your computer between removal attempts.

Spybot Search and Destroy will prompt you to reboot and attempt
removal during the reboot if it encounters a particularly
stubborn bug.

4. In some cases, no amount of scanning/cleaning/rebooting
can remove the malware. In this case, you have two options:

a) Boot the computer into "Safe Mode" and re-attempt the
   Spybot and Microsoft scan/removal process. (To get your
   computer to boot into Safe Mode -- press <F8> just after
   restart -- and select "Safe Mode" from the boot menu.)

   This may allow you to remove applications that are run
   automatically at start-up, but that protect themselves by
   preventing the file from being deleted while the bug is
   running.

b) Boot the computer into Safe Mode, Run "Regedit" or
   "Regedt32" and try to clean the parasite by searching
   the registry for strings that the anti-virus programs
   have found.

   Note: I won't provide detailed instructions on registry
   editing -- because if you don't know how to do it already
   -- you'd probably better not try! It can mess you up.
