Not while in the menu's or loading screens but only when I actually join a server.
A command prompt windows opens and shows the following:
[INFO] Blocked loading of file: "C:\Program Files (x86)\ASUS\AI Suite II\TurboV EVO\HookKey32.dll".
AI Suite and TurboV EVO are legitimate ASUS motherboard monitoring applications that come with all ASUS motherboards.
I use it to overclock my CPU and monitor temps etc.
