I had PUM.dns latch onto my computer and I've tried secure erasing the SSD. However, even that has not stopped the issue of it inviting various trojans back onto the computer.


I remember seeing a message - 'Secure Boot Violation: The system found unauthorized changes on the firmware, operating system or UEFI driver...' and considering resetting/flashing the Bios to see if I can remove any potential issues with its integrity.


Would anyone know if this is effective or recommend a better way in dealing with this issue? 


I have an ASUS Z97 and they do have this flashback option with a USB. Is that useful?


Appreciate any comments.
