Microsoft Security Essentials Unable To Remove Trojan:Win32/Dursg.C Found In lsass.exe

A client called me today saying that a computer I had recently removed the Personal Security Virus from now appeared to have another virus. I was surprised by this since I had left Microsoft Security Essentials installed and active. My first thought was that he must have disabled the virus software however when I started looking at the laptop this was not the case. Below I describe steps I took to resolve the issue that were unsuccessful in remove the Trojan:Win32/Dursg.C as well as what I finally did that resolved the issue.
