Hi there!
I did had the same problem! And my pc got VERY slow becouse of this program...
Its starting itself from the registry, when you try to delete it, it comes back automatic immediately in the registry....
To remove it:
- Reboot youre computer
- Start windows in safe mode (F8 during boor)
- Start Run -> regedit
- Goto: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
- And remove the anoying 'msnlogm.exe' program!
- Reboot, and it is gone
Good luck!
