Security and anti-virus software maker McAfee conducted a recent study of the five major search engines in the U.S., including Google, Yahoo!, MSN, AOL, and Ask.
This is the second year of the now annual study, and the update indicated that although the overall safety risk to search engine users had declined by about 1 percentage point, it was the sponsored results (those paid for by advertisers) that continued to incur the most risk.
The study analyzed the first 50 search results returned by each search engine for 2,300 popular keywords, with each result then compared to McAfee SiteAdvisor's Web Safety database of 8.2 million site safety ratings.
The ratings were broken out into two categories, red and yellow.
