Trojan.Fileless.MTGen is Malwarebytes’ generic detection name for the startup locations in use by fileless infections that gain persistence by creating these registry keys on Windows systems.
In the majority of the cases, the registry keys created by Trojan.Fileless.MTGen are designed to run Powershell commands that carry out the rest of the infection. Other than Powershell, we have also seen the mshta command used as such.
Malwarebytes protects users from Trojan.Fileless.MTGen by using real-time protection to block the Trojans that create them.
Malwarebytes can detect and remove Trojan.Fileless.MTGen without further user interaction.
