Hmmmm.... I think you need expert help at some malware removal forums.
If I am in your place, I will go for an easier route, that is, a reformat n fresh install of OS.
+1, this is a nasty one, (or windows is just idiot again

)
I'll do a last try, but a reformat will be a lot faster
Try
this tool, unrar it and update it, then set the heuristics to extreme modus and let it scan (for hours

)
Afterwards, see what it detects
