Hello. I uninstalled Norton, and the last step was letting it restart my laptop (m18 r2). Then when I did this I got hit with a BIOS update. I have never, in decades of computing, had a BIOS update pushed-in fact I've only ever done it once and that was manual. Should I be worried that Norton did something fishy? How can I tell if this BIOS is an official update? Thank you.
