How am I meant to trust Norton for my internet security when you can't even get your ad serving right? When your video ad plays on YouTube, you include an insecure tracking component, causing my browser to trigger the "mixed security" icon. Has no-one in Norton marketing heard of QA or attention to details? And no-one who works at Norton has ever noticed this while browsing YouTube and reported the issue internally for correction? A trivial thing to correct, btw.
Full disclosure: I am not a fan of Norton security. It is my least favourite (major) anti-virus solution for reasons of resource consumption. But this kinda of oversight strikes me as below them.
