Pay attention to the part about scanning in Safe Mode. Makes a huge difference in whether the trojan gets completely removed.

Start machine and tap the F8 key; you have to hit it right before the windows logo shows, so I just tap it repeatedly when I know it's coming soon.

Then select 'safe mode with no network'
Then scan.
This prevents anything but basic windows components from starting. Your screen will look bad, and it may be a bit cumbersome to find menus .. but this way the virus doesn't get a chance to start up and hide copies of itself so it can load again later.

I do not work here, but the benefits are still awesome
