I am running Windows XP. I have recently installed Microsoft Security Essentials on this computer. I am not happy with its features and functionality and so would like to uninstall it. I will be reinstalling my Norton antivirus. So I want to know how to clean uninstall Microsoft Security Essentials from my Windows XP computer? I am asking it because I have tried to uninstall it but it doesn't get removed completely. I can still see its folder appearing in Programs folder.
