Trying to remove all traces of Systems Center Essentials 2007

I installed Systems Manager Essentials 2007 trial software a few weeks ago...

I would like to get rid of this software.  

I ran through the uninstall referencing this article:
http://technet.microsoft.com/en-us/library/bb437343.aspx

I then ran through the steps in this article:

I am still seeing Operations Manager logs on my servers with errors:
