Some Game Trainers are sometimes reported to be a Virus or Trojan, the most common is a keylogger called HotKeysHook or the file has been packed/protected with VMProtect or Themida and is recognized as Win32/Packed.VMProtect or Win32/Packed.Themida. In ALL cases this is a FALSE ALARM as NONE of the Game Trainers @ GCW contain known malicious code! More info in the PC Games FAQ!
