I've recently downloaded the crimson 16.1 version and was unable to download it because the publisher was unknown???? Even though my Norton security suit verified the publisher, Internet explorer or any other web browser could not. This has never happened to me before on this website before when updating drivers.
Norton's is wrong--got to be a Norton's bug if you are downloading from the AMD site. You are much better off getting that junk off your computer completely and sticking with free Defender in Win8/10. It's much more user-friendly and probably does a better job, too--especially when it comes to this kind of false positive.
