It may be that the instructions aren't stopping everything.
In some cases, there's a program running out of the Program Files/Program Files (x86) directory.
"c:\program files\qualcomm atheros\killer network manager\killer~1.exe" (NOTE: killer~1.exe is most likely killernetmanager.exe)
In other cases, there's a program running out of c:\windows\installer\{Long string of letters, numbers, and dashes}\networkmanager.exe_130c27d738f34c89bddf21bcfd74b56d.exe (the long string of letters and numbers may change)
Here's some things to try
1) Please see if there are any entries in the Startup tab of Task Manager that are related to Qualcomm/Atheros/Killer Network Manager (and NOT the card itself) and disable them (please let us know what you find) Be careful as the wrong selection can disable the network card.
2) Check in "msconfig" for any entries that aren't in the Startup tab of Task Manager. Let us know if you find any Qualcomm/Atheros/Killer entries there (we'll disable them differently if they are there).
3) Locate the "c:\program files\qualcomm atheros\killer network manager\killer~1.exe" and rename the .exe to .BAD (the killer~1 is actually a filename that starts with killer and ends with .exe) There will be an error in event viewer, but it'll stop the bugger from loading.
4) Locate the "c:\windows\installer\{Long string of letters, numbers, and dashes}\networkmanager.exe_130c27d738f34c89bddf21bcfd74b56d.exe" entry and rename the last .exe to .BAD (the long string of letters and numbers may change)
Just FYI - here are the MSI workaround instructions:
