If you do an SSL check on that domain everything comes back green so I don't know why McAfee would label it as "malicious" as they have no reason to. I would file a false positive report with McAfee and ask that they remove this from their blacklist. Obviously it's not all AVs and systems that have a problem with the URL or we would have THOUSANDS of people complaining that they couldn't update, including myself.

Oh trust me I know, McAfee is just dog ****. I trust y'all more than I do scummy Verizon anyway.
