Actualizacion de "secure boot dbx"

Hola, me pueden ayudar con un tema relacionado al "secure boot", tengo una actualizaciòn que no se puede completar o realizar

El error que se presenta es:
"This updates the list of forbidden signatures (the "dbx") to the latest release from Microsoft.

An insecure version of Howyar's SysReturn software was added, due to a security vulnerability that allowed an attacker to bypass UEFI Secure Boot"

gracias

You can also look if there are BIOS-updates on your manufacturers site to update your BIOS/UEFI.
