Only if you give me a coin also...
well, try to validate your files... if that does not work then completely remove the game by uninstalling from steam and also removing the "Rust" directory from Steam\steamapps\common\ then re-installing. Good luck
Smart choice there... have you tried to disable it and start the game?
What virus software do you use?
You added rust and EAC to your antivirus software trusted programs list?
Use google before asking for help here please, thanks! G.O.O.G.L.E
