Something to try.
1. Disconnect from internet immediately.
2. Ctrl Alt Del to open the task manager and attempt to find the dll/exe that is running the process. Turn off everything you can, esp tray icons to minimise search.
3. Turn on "view system files"
4. Search for the offending file.
5. Open file location and attempt to delete it. Chances are it won't.
6. Turn off "System Restore (Vital step)
7. Reboot in safe mode, log using the administrator login.
8. Delete files
9. Reboot.
Fingers crossed, let me know how it goes.
