Microsoft Security Essentials Removal Tool
This download allows you to uninstall Microsoft Security Essentials if you cannot uninstall it in Control Panel by using the Add or Remove Programs item or the Programs and Features item in Windows Vista and Windows 7.
We recommend that you verify that you cannot uninstall by using Add or Remove Programs first.
Note: You must be logged on to Windows by using a user account that is a computer administrator to complete this method. If this is your personal computer, you are likely already logged on by using an administrator account. If this is a computer that is part of a network, you might have to ask the system administrator for help.
