The world's most dangerous search terms

Yesterday, McAfee Site Advisor released its yearly report on "The State of Search Engine Safety."

Gossip lovers are another frequent target: The combination "Brad Pitt + Jennifer Aniston," for example, often leads to dangerous web ambushes. The work of overeager Jolie fans, perhaps?
