Question : Vista DLLHOST.EXE Popup

Experts -

I am currently working on a computer running Vista Home Premium. When you go to the control panel or other places in explorer, it will constantly flash a CMD window with no body, just c:\windows\system32\dllhost.exe. I've ran Malwarebytes and ccleaner on it, it was infected, now the infections are gone, i'm currently running combofix on it, but i was greeted by an access is denied to certain features. Has anyone seen this before?

Probably better off, timewise :)

Did you try running System file checker at any stage? Although being Vista....!
