There is no such thing as Mydoom-C. The thing which media calls by this name is actually completely different virus. It does not spread via email or P2P, only via the backdoor installed by Mydoom-A worm. This worm is called Doomjuice by all AV companies, including avast! which detects it since Monday.
The internat.exe is valid Windows application. The name used by Doomjuice is intrenat.exe (some letters swapped)
hope this helps
