Frankly, I find McAfee's presence on the web an invasion, and you're association with them gives me no warm fuzzies.
They profile a website on their Site Advisor: e.g.
McAfee Website Advisor
They give a huge X!
And then were do they declare anything wrong with the site? NOWHERE?
How dare they?!
So they tag a site with a warning?! And yet they do not tell you why??
Who would page $64/mo for that?
