Cameron Diaz is the most dangerous celebrity on the Web, antivirus company McAfee said Thursday.
Search strings using Diaz's name have a one-in-ten chance of coming up with a site infected with or spreading malware, said Dave Marcus, McAfee's director of security research and communication. Search for "Cameron Diaz and screensavers," and the risk doubles, Marcus added.
As it has for the last three years, McAfee compiled search phrases that contained names of prominent celebrities, professional athletes, politicians and other newsmakers, then calculated the percentage of the resulting sites tagged as dangerous by the company's SiteAdvisor software.
SiteAdvisor is a free plug-in for Microsoft's Internet Explorer and Mozilla's Firefox that flags risky sites -- those serving up malware, adware, spyware and the like -- in a search result list.
Diaz replaced Jessica Biel, last year's top name bait. Biel fell two spots to third on McAfee's list this year.
Actress Julia Roberts placed second on the Most Dangerous list, while supermodel Gisele Buendchen took fourth. Brad Pitt, the highest ranking man on the list and one of only two on the top 10, held the fifth spot.
"It's a simple fact. The bad guys read the same news as the good guys," said Marcus as he explained why some celebrities ranked higher than others. He attributed Diaz's prominence to the fact that McAfee's list was composed around the time when she was in two currently-showing films, "Knight and Day" and "Shrek Forever After."
Attackers and scammers trade on the names of prominent people and topical events to dupe users into visiting malicious sites, to open malicious e-mails, and to click on malicious links embedded in Twitter messages, said Marcus.
