Setting Up the Windows System Shields

You can set up Spy Sweeper to continuously monitor several Windows system settings. These are settings that some spyware, adware, or unwanted programs change if you are not protected.

If the shields are unavailable (dimmed), you may not have access to this function. For more information, see Understanding How Spy Sweeper Works with Multiple User Accounts.

To set up Windows System Shields:

Start Spy Sweeper, if it is not already open, and display the main window.
For more information, see Starting Spy Sweeper.
In the icon panel, click Shields.
For information about the Spy Sweeper window, see Understanding the Spy Sweeper Window.
The Shields panel displays, showing a summary of the available shields and their status. A check mark means the shield is turned on. An x means the shield is not turned on.
Click the Windows System tab.
The Windows System tab displays.
Select the options you want to use.

Option	Description
Memory Shield	This option sweeps your computer's random access memory (RAM) frequently looking for spyware, adware, or unwanted programs. It only sweeps memory when Spy Sweeper is open in the system tray in the lower-right corner of your screen (minimized).
Spy Installation Shield	This option actively watches for programs that try to install themselves on your computer. Whenever a program tries to install itself, Spy Sweeper lets you know and gives you the option to accept or reject the change.
ActiveX Shield	This option actively watches for programs that install ActiveX technology on your computer. Whenever a program tries to install ActiveX technology, Spy Sweeper lets you know and gives you the option to continue the installation or to stop it. ActiveX technology is a group of functions developed by Microsoft that let programs share information. Many legitimate programs use ActiveX, but some spyware, adware, and other unwanted programs also use ActiveX to install themselves.
Only Prompt Action for Known Spyware Items	Select this option to have Spy Sweeper watch for only known spyware that tries to install ActiveX technology. Turning this option on will reduce the number of alerts you receive, but could permit new spyware (that is not yet in the Spy Sweeper definitions) to install.
Spy Communication Shield	This option actively watches for communication from your computer to known Web sites that are related to spyware, adware, and other unwanted programs. Spy Sweeper includes a list of known sites with its definitions. If Spy Sweeper detects an attempt to communicate with a site on the list, it will display a pop-up alert in the system tray (lower-right corner of your monitor) telling you that access to the site was blocked.
Alternate Data Stream (ADS) Execution Shield	(Applies only to Windows NT, 2000, and XP.) This option actively watches for programs that try to start from an alternative data stream (ADS). ADS is a highly technical way to hide images, data, or code in a file and can be used to hide malicious code. The hidden content is impossible to detect using regularly-available tools, such as Windows Explorer. Turning on this shield lets Spy Sweeper alert you if a program tries to start from an ADS.
Windows Messenger Service Shield	(Applies only to Windows NT, 2000, and XP.) This option turns off and actively watches the Microsoft Messenger Service. This service is not an instant messaging program and does not affect your use of instant messaging. This service is often used for sending spam (unwanted e-mail) and creating pop-up ads. Turning off the service stops these types of spam and pop-ups. If your computer is in your home, you can turn off this service without any problem. If you work in a corporate environment, contact your system administrator to find out if your company uses the service to communicate with company employees. If you are not sure, leave the service turned on until you find out.
