Trojan.Malpack is Malwarebytes’ generic detection name for Trojans that use custom packers to obfuscate their code. This concerns packers that are normally not in use for legitimate purposes. So the detection is purely based on the way the file is packed—the payload could be anything.
Malwarebytes protects users from Trojan.Malpack by using real-time protection.
Malwarebytes can detect and remove Trojan.Malpack without further user interaction.
