Fake Microsoft Security Essentials Warning

I had an interesting thing happen the other day while trying to remove malware from a client’s PC.  I knew the system was infected, but I also kept getting a warning from what I thought was Microsoft Security Essentials.  Turns out it was a fake virus warning.  It would pop up whenever I rebooted the computer as well as when I tried to run Task Manager, Malwarebytes, and other programs.  I finally found out that it was a fake MS Security Essentials warning and was able to find a post on www.bleepingcomputer.com that gave me instructions for its removal.  The link is listed here for anyone who needs it.  I tell you what, that sucker was anoying.  I used the info here to rename mbam.exe and combofix.exe to something else so that I was able to run them  After doing that, they worked like a charm.
