Microsoft Security Essentials

Step 1

First you will want to download and run the Microsoft Fix it tool from here: http://go.microsoft.com/?linkid=9775235

microsoft-fix-it

Step 2

In our instance, the Fix it tool doesn’t clean/fix everything and we still need to delete a certain registry entry. So go to the start menu and launch “Regedit.”

regedit

Step 3

Now browse to the following location. One of the folders under the “Uninstall” folder will contain a Microsoft Security Essentials entry on the right hand side. Delete that one.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current version\Uninstall\

regedit-uninstall

Step 4

Reboot your computer, and hopefully the error is now gone.

      Go into msconfig from Run Dialog box and disabled Microsoft Security Essentials from Start Up. I would recommend that you use a good third party tool for your PC Protection.
