Many computers come with a free trial or subscription to a McAfee security product. If you have been using one of these products and your subscription expired, you can uninstall it using a combination of the built-in Windows program removal utility and a removal program that McAfee offers. Because the Windows program removal utility isn't able to fully clean your system of the McAfee program, the company released this tool to allow you to fully clean your system of its software.
Click "Start," "Control Panel" and "Add/Remove Programs" if you are in Windows XP, or "Programs and Features" if your computer uses Windows Vista or Windows 7.
Select the McAfee product from the program list (such as "McAfee SecurityCenter") and click "Remove" if you are in XP or click "Uninstall" if you are in Vista or Windows 7.
Wait for the software to be uninstalled and then restart your computer when requested.
Open an Internet browser and download the official McAfee Removal Tool (see Resources). Double-click on this tool to run it if you are in Windows XP, or right-click on it and select "Run as Administrator" if you are in Vista or Windows 7.
Once you see the message "Cleanup Successful," you can restart your computer again and the McAfee product you were removing will be fully uninstalled.
