Not sure, the CPHL site did get infected, but we've removed Joomla entirely so that was cleaned up, and the rating seems to be for the specific domain.
Checked on that and the www.calgarypuck.com
and cphl.calgarypuck.com come back fine, but the forum doesn't. But checked with the securi scan and that comes back with no infections.
Sometimes people post pictures or URLs to sites that have a bad reputation and the scanners pick that up.
I guess the only thing to do is I'll use that McAfee form to submit a request to reclassify or give more details.
