Trojan.ModifiedMS is Malwarebytes generic detection name for Trojans that are present on affected Windows systems as altered Microsoft files.
The files detected as Trojan.ModifiedMS will be signed by the actual Microsoft Corporation, but are no longer the original files. A malicious payload will have been added to the file.
Malwarebytes protects users from Trojan.ModifiedMS by using real-time protection. At the moment there are no files detected as Trojan.ModifiedMS in the wild.
Malwarebytes can detect and remove Trojan.ModifiedMS without further user interaction.
Malwarebytes cannot always replace the removed file with the original, so users may want to run the Windows System File Checker after the removal has been completed.
