Hi
"Here's what I do see. SpyBot is showing only one item after S&D: "MicrosoftWindowsSecurityCenter_Disabled.""
That's ok, no worries.
"Also in SpyBot under Startup, there are three entries that will not go away:
Windows/System32/awtqq.dll
opnmkii
Windows/System32/pmnlk.dll
If I toggle them off, they reset to ON, and if I remove them they reappear."
Try to uninstall & re-install spybot. Now success?
