If you arrived at this post directly please check out the EzineArticle on this that explains how this type of attack works.   Here are several steps to take.

  1. Firewall; since there are multiple ways to disable and stop a Firewall from doing its job it is important to have a robust firewall installed on the computer.  There are at least three 3rd party firewalls, free for use on a personal computer, that meet this requirement.  We have quick links available; to reach them please create a free user account via the sign-in page and locate the Firewall Button to access information on each one and to download.  [For reference; the 3rd Section of the C.A.L.M. Manual has detailed instructions on how to install this Software.]
  2. Testing; once the new Software is installed you can test how well your computer ports are protected.  These are the doorways into your computer from the Internet.  Log-in with your newly created user account and click on the Firewall Testing button for detailed instructions.

Be sure the Windows Firewall is disabled once the new Firewall is installed.  To verify go to the Control Panel.  Windows XP; Left-Click on Start, Left-Click on Location of many Windows Utilities and when it opens Left-Click on Windows Firewall.   If not already set, select the OFF (Not Recommended) option, not to worry since the 3rd Party Firewall is now serving this roll.  And to verify this close all these windows and locate the Firewall Icon in the Systray at the bottom right of the computer.  Double-Left-Click on it or Right-Click on it and Left-Click its control panel from to the pop-up menu to open.  This new window should give the current status of the Firewall.  Windows Vista; Left-Click on Left-click and start typing for quick access to files and utilities! and type in Security Center, press ENTER.  Left-Click on Windows Firewall and choose the option Vista Turn-off Firewall and ignore any warnings that appear.  [See the Firewall 3rd Section in the Manual for more detail.]

Detail Firewall Testing instructions are available in the free-to-register portion of the website.  The 3rd Party Software is included since it is free for home use, enjoys a strong user approval and has tested top of its class in defeated outside kill tests.
