I get it when I use google to search FR for Clinton scandals like this google search:
site:www.freerepublic.com "larry nichols"
Otherwise no problem -- though I suspect searching for anything connected to Clinton scandals (and probably Obama scandals) will "harm you and your computer."
If I use FR's search for keyword, larrynichols, appears to be no problem.
All of the above is based upon minimal investigation. But using google to search FR for "larry nichols" appeared that every FR thread was tagged with the warning.
