Today we’re shipping changes to CS:GO that are part of our continuing fight against cheating. CS:GO now significantly restricts the types of programs and files that can interact with the game. By default, players will launch CS:GO in Trusted mode, which will block third-party files from interacting with the game. If you would like to play while using third party software that interacts with CS:GO, launch with the -untrusted launch option. Note that in this case your Trust score may be negatively affected.
