Based on your post I was able to get the warning via this address:
https://www.google.com/interstitial?url=http://www.freerepublic.com/focus/f-news/3198639/posts
And that leads to this:
Apparently someone has posted links/images to threads that are to unsafe URL’s. The actual malware isn’t being hosted by FreeRepublic.com directly.
I found the offending img link on that thread and pulled the reply in question.
I performed the same search on Pale Moon, using ixquick search engine, no problem, so I went to google and FR link did not even show up, lots of links to Mediaite, The Blaze, Facebook, but no FR.
This is the first time I've used google in well over a year.
