How do I get Mcafee to stop warning me about a website?
Well here's what I came up with. Go into VZ Protect, in Security click the gears you see next to Status and scroll to the bottom and there you will see a switch to turn off the McAfee SiteAdvisor. I didn't really like this solution but submitting the website to McAfee as a non malicious got me nowhere and as you point out Chrome will tell you if you've landed in a scary place.
Get rid of McAfee. Google Chrome does the warning all on its own.
