Delay due to spyware

On Sunday I had one of the most complex spy or virus I ever had. I had the virtumonde.dll spy and Spybot, Adaware, Spyware terminator, didn't work, so I downloaded combofix.exe it turned my desktop to black and the icons have only the description, I don't see the image of them, ie doesn't work, I spent the afternoon trying to restore my machine but at the end I have decided to format, so I will try to make the videos on my laptop.
