Tough Lefty writes "A new study by McAfee's SiteAdvisor Web ratings finds that sponsored results from some of the biggest names in the search engine business contain spyware, spam, scams and other Internet menaces. The key findings were that major search engines returned risky sites in their search results for popular keywords and sponsored results contained two to four times as many dangerous sites as organic results. Overall, MSN search results had the lowest percentage (3.9%) of dangerous sites while Ask search results had the highest percentage (6.1%). Google was in between (5.3%).
