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.

Here is how you can uninstall Microsoft Security Essentials from your computer. Download the MSE installer file and save the file on your desktop. Now press the Windows + R key at the same time. This will open the RUN dialog box. Now drag the MSE installer file into the RUN dialog box. It should appear like this C:\Documents and Settings\[YOUR USERNAME]\Desktop\mssefullinstall-x86fre-en-us-xp.exe. Put a SPACE at the end of the line, followed by a "/U" (C:\Documents and Settings\[YOUR USERNAME]\Desktop\mssefullinstall-x86fre-en-us-xp.exe /U). Now click on OK button. Reboot your system after the uninstall is completed.

First check if you meet the Microsoft Security Essentials system requirements. For you can check Microsoft website and see what is stated in the minimum system requirements over there. This may be the reason why you are not getting appropriate MSE features and functionality. The below is the list which Microsoft recommends for a computer to meet in order to use MSE fruitfully.
