Can you find the registry entries in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services? If so, the actual file loaded should be listed in the parameters key. If there is no parameters key, then it is likely that the service has already been partially deleted by an AV program. If the paramters key points to a file and its location, then verify that the file is at that location.
Report back what you find.
