*** ANTI-VIRUS INFO ***
Microsoft Defender Anti-Virus / Smart Screen (and possibly a couple others) will detect this as a virus & you'll have to allow it to download and run. It's not a virus or trojan and will not allow attackers to hack your computer. Most Anti-Virus software will not throw any warnings.

This app works by modifying your computers hosts file so that it can redirect traffic sent to Novaworld back to the app for verification. It opens a local UDP server so that the client (the game) can verify itself with the app, mimicking how Novaworld verifies clients. The UDP server is only available while the app is running and the modified hosts file is restored once you close the app. The UDP server won’t allow remote attackers to hack your server and does not send any information to any remote location.

Modern virus scanners can detect the functionality of apps before they are run and from their analysis it certainty seems sketchy. I did not program any backdoors, trojans, viruses or personal data collection into this app. However, if you do not trust software, you should not run it.

INFO:
NW Authenticator allows you to host LW/TFD/BHD/C4 even when NovaWorld is down. If you get an "Unable to host a Session" message when trying to host a game, most likely NovaWorld is down and another method to authenticate your game will be required. Open this tool before loading your game and it will attempt to locally authenticate your games session. If you get an "Unable to Host a Session" message when hosting, this is what you need.

Your game will still appear on NovaWorld. Please ask for help in the forums if it does not work for you.
