1. Uninstall Daemon Tools via Add/Remove Programs.
2. Download the SPTD standalone installer and perform the following steps.
3. Double click the executable to open it.
4. Click the button shown below.

   Information

If the button it is grayed out as shown in the image, there is no more SPTD installation on your system and you can just close the window.

Hopefully that will cure the issues, keep us posted.

It's the Atheros driver again, not sure why it's showing a different number reference maybe it's just part of the same driver package.

Make a Restore Point and try the AR8171 Windows 8 driver from here.

I didn't see that driver anywhere in the dumps. That's a Windows driver so it's probably a false positive.
