Your antivirus flags the steam_api.dll file as high risk, possibly because it's related to a problem. If your game fails to launch and the antivirus says it can't start the program due to a mismatch, it might be a genuine issue. It's not just a normal file—your protection system is flagging it, so you should investigate further before taking action.
