RunDLL error and unable to delete registry keys?

Hello Experts,

I have a Windows 8 computer that upon bootup for the last 3 weeks or so, right after upgrading to 8.1, I've been getting this error and I've done everything I can to get rid of it and it just keeps popping up when I boot up the computer.  Here's what the error says:  
"There was a problem starting 'C:\Users\username\AppData\Local\Conduit\BackgroundContainer\BackgroundContainer.dll' The specified module could not be found."

I've gone through the C: drive and cannot find any traces of anything related to "Conduit", "BackgroundContainer" or anything of that nature.  I went through the registry and found two "BackgroundContainer" startup keys, but it won't let me delete them.  I tried running regedit as admin, I've tried booting into safe mode and running regedit as admin and nothing is working.  I just keep getting the error, "Error deleting values:  Unable to delete all specific values" when I try to delete the keys.  I've tried running malwarebytes full scan as well as CCleaner full scan and neither fixed it.  How do I get rid of this annoying and persistant popup error??

It looks like the "Conduit" malware was removed from your PC, but left entries in the registry.

jboddy,

This solution is very accurate and I thank you for that, but the one major issue is that once I follow that instruction guide on removing those registry keys, upon reboot, all of the user's start menu icons are wiped out and all their documents on the desktop are gone.  Basically everything gets deleted and rearranged after performing this action.  I did a system restore to get all of their stuff back because they were freaking out which then caused me to freak out and I just wanted it to go back to the way it was due to the freaking out episode.  Following the system restore, everything was back the way it should be, but the malware was also back too.  Is there anything I can do to make sure this doesn't happen while still removing the malware registry keys?

Have you checked the permissions on the reg keys?

Sorry about not replying, been very busy at work.
I am not sure where I was going with the permissions suggestion as I have had too much to drink since then!

I cannot recommend Malwarebytes (as listed in the above link) enough, it has got me out of several holes!
