We need to talk LTT. It is the widespread opinion of many industry experts that any Windows antivirus, apart from the built-in one, does much more harm than good. I understand that your viewers are more savvy than most, but even savvy users still believe that a 3rd-party antivirus is a good idea. Please do some research on this subject, possibly even share it as a video, prior to an antivirus sponsorship spot (once you'd clued-in your viewers, take the sponsorship money by all means).
