Scenario: Dell XPS 8700, Windows 10 Pro 64 bit, fully updated. Avast Premier, Malwarebyes Premium.
After backing up all data and imaging the system, etc., I went to the Dell support site. First I downloaded and installed all the pending drivers (there were 5, because I hadn't done that in a very long time). Then I downloaded the BIOS update A12 (the Spectre patch). The BIOS on the machine was A08. After closing all open programs I launched the executable BIOS update. This went ahead in what seemed a normal way until it got to "Flashing ME now, please wait..." That proceeded fairly quickly to 99% - and it has been stuck there now for at least an hour and a half. Question arising: what to do? Will this eventually clear itself and go ahead? Or is this a hopeless catastrophe? Or is there something I might do to "unstick" it?
EDIT - this situation is still unchangd 12 hours later.
Needless to say I am posting from a different computer (my laptop).
I think I did something stupid, i.e. I failed to disable memory-resident monitoring programs (Avast, Malwarebytes,Wiinpatrol, CCleaner etc.)
FWIW I do have a bootable rescue disk, created by Macrium Reflect 7.
