A human error has been made at Google. Early today, each search result returns a warning that each of the site listed in the reults may harm the searcher’s computer. If a user clicked on a search result, a Google webpage will show up which gives a warning and it also prevents the user on reaching the result’s URL.

Two screen shots are included in The Register’s article. The first shows a sample of a search. The other shows the warning once a user clicks on any of the result links.
