Well, if I understand well what my colleague told me, the problem is that the "evil update" replaces some dll file that is essential for AMD cards, so this "fix it" package should replace the broken dll file by the original one.

When the package doesn't work, the second advice was to reinstall the graphics card drivers. It should remove the broken dll and put the correct one there (I'm not sure whether you haven't already tried it)

Advice #3 was to disable automatic updates (http://www.techtalkz.com/windows-7/515869-windows-update-enable-disable-automatic-updates-windows-7-guide.html) and then to uninstall the KB2670838 update.
