To try to identify and remove deceptive software from your computer, use one or all the following methods.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

Note If you use an operating system that has the System Restore feature such as Windows Millennium Edition and Windows XP, set a valid restore point before you follow these steps. You can use the restore point to restore to the computer configuration that you had before you made the changes if you do not want the changes.

Note Deceptive software programs may not follow standard practices for installation. Therefore, the software may not be found in the locations that are described in the following steps.

1.	Click Start, and then click Control Panel.
2.	Double-click Add or Remove Programs.
3.	In the Currently installed programs list, find programs that you do not recognize or are named similarly to the program that is causing the unwanted behavior. Note Some programs that have unfamiliar names may not be deceptive software. Some programs may have come preinstalled on the computer from the manufacturer or may be important components of other software that you have installed on your computer. We recommend that you use caution when you remove programs from your computer.
4.	Click the program that you want to remove, and then click Remove. To remove the component, follow the instructions that appear on your screen. You may have to restart your computer.

Find the program folder with Windows Explorer

Some programs do not register with Add or Remove Programs and do not have a Start Menu folder. These programs may have a folder on the hard disk drive where the program that you want to remove is installed. This folder may contain a file that you can use to automatically remove the program. To find the program folder and remove the unwanted program, follow these steps:

1.	Click Start, right-click My Computer, and then click Explore.
2.	Expand the folder tree to look for a folder with the name of the program that you want to remove or the name of a program that may have included the program that you want to remove.
3.	When you find the unwanted program's folder, click the folder.
4.	In the right-pane, if a file to remove the program exists, double-click that file. For example, the file may be named Unist.exe, Uninstall, or Uninstall Program_Name.
5.	Follow the instructions that appear on the screen to remove the program.

Note If you find a folder for the program that you want to remove, but you do not find a remove file to remove the program, do not delete the folder or the contents of the folder. If you delete the folder or the contents of the folder, you may adversely affect your computer performance and operation. For example, Windows may not start, programs may not start, or programs may stop running.
