You can try to install the software mentioned in the link, or you can try these manual steps (not guaranteed to work though):
1)  Kill the msnlogs.exe process
2)  Delete the file from C:\Windows
3)  Check and delete any references to the file in the registry:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
4)  Check and delete any references to the file in Windows startup folder.
