As already stated in http://fougerite.com/threads/found-external-radar-program.1339/
The current RustBuster Client 1.5.1 is producing a false positive which seems to affect almost all players.
I already messaged Dretax about this problem. There is no workaround available. We have to wait until Dretax comes online.
Edit: This problem has been fixed with RustBuster 1.5.2
