Advanced Onion Router is a client for the TOR network that can anonymize applications without the need of a configured proxy required by most TOR clients. AOR is intended to be an improved alternative for the TOR+Vidalia+Privoxy bundle, able to “force” a program and its plugins to use the TOR network. It is used in windows.
