So far, Kaspersky has left all my sites as gray, as apparently it doesn’t rate “amateur” sites. On one Windows 8 machine, I have Trend Micro, and Trend right now is not showing ratings (maybe I haven’t tweaked enough). McAfee has always rated me green. Most of the time MyWOT is OK, but I do show a lot of unknowns.
It does not appear that the use of Adsense affects safety ratings. But third party ad-ons available for Blogger might, as could some issues with various Wordpress plug-ins and templates.
I tried a few of my sites in Norton Safe Web, and found they had not been rated.
None of the sites give warnings (from Webroot, Trend, or Norton) when I go to them. However, I know of one incident where a book publisher's site gave a phishing warning from Norton,, only on older versions of Windows, that turned out to be false.
