Microsoft Windows NDIS proxy that should be located in the C:\Windows\System32\drivers directory.
NDProxy should be a system process, however some DNS changers can add their own NDIS proxy devices redirecting to rogue DNS servers. If you don't trust your Windows system perform an "sfc /scannow" on the command prompt and allow it to restore modified system files.
NDPROXY is a system-provided driver that interfaces NDISWAN and CoNDIS WAN drivers (WAN miniport drivers, call managers, and miniport call managers) to the TAPI services.
