I got the Exploit Blackhole Exploit Kit warning too, just visiting a persons profile. Oddly, I realized I wasn't even logged in yet, I had just gotten to hubpages. This concerned me that anyone visiting the site could find this immediately.
I feel fortunate that my security caught it. I hope to be reassured soon that this will end, so that others don't consider this a site to avoid. I know others have worked so hard as well to put a lot of original content here and hope this is the first and last time I deal with it.
I have not had all the others that I have heard about. Just this Ex. Blackhole Exploit one.
Yes, I wonder that as well, paradigmsearch. It was viewing a profile only, then it showed up. I am confident the HP team will address and then share the answer with us so we don't have to be wondering if it will happen in the future, surely?
