Need help with ZeroAccess Infection Windows 7 64 bit

I now need some expert help with a friends computer. I'm new with Windows 7, but it works like vista.

The computer would not boot under windows normally so I booted under repair mode. Then I rebooted normally.

Then I uninstalled the non working Norton Antivirus, and installed Avast.
Ran a quick scan with avast, then I knew this computer had real problem, that was not so easily repaired.

This is enough rambling on my part.
Here are the logs needed.

 

Because of the nature of this infection, the best course of action I can take would be a reformat and reinstall of the OS.

Thanks anyway.

 

I did the reinstall yesterday.
Thank you anyway, It's nice to know help is here when needed.
