Phew, we'd not heard of anyone else with this issue but it still made me a little worried when you mentioned the problem. I'm pleased you've got it working now though, thanks for letting us know.
You might want to talk to Mcafee about their classifying your site as dangerous, or just curse them out like I've done when they listed my software as malware. For what it's worth, they do the same to emacssurvey.org so it's not just you :)
