SiteAdvisor is a browser plug-in so it's user opt-in. I can empathize with you but unfortunately the Internet is full of users that are not security-savvy and thus they have to rely on a trusted entity, e.g., McAfee to make security decisions for them. Unfortunately, perverse incentives can creep in like what you experience; McAfee slow to aid your cause. I'm developing 'visible security', a 'product' that provides information to a user for her to judge the risks of visiting a site, e.g., number of 3rd party components/APIs a site relies on, etc. and selectively control what she wishes to retrieve from a site. For your particular case, 'visible security' can help in 2 ways: (1) a user has control to not download that particular component but yet view your site as per normal, and (2) even if McAfee flags your site as bad, with 'visible security' being vendor-neutral, other more responsive vendors or a ton of registered Internet user may flag your site as good thus sending a strong signal that McAfee may just be over-cautious, etc., thus liberating sites from the mercy of a single security vendor that has a large user base.
