Heidi Klum has replaced Cameron Diaz as the web's most dangerous celebrity, says McAfee.

Research by the security firm revealed that web users searching for the former Victoria's Secret model and wife of pop star Seal have nearly a ten percent chance of navigating to a site laden with malicious software. 

Last year's most dangerous celebrity on the web, Cameron Diaz, took second place in this year's list while former Daily Mirror editor best known for his role on Britain's Got Talent, Piers Morgan, was third. The top five was completed by Jessica Biel, former sweetheart of Justin Timberlake, and Grey's Anatomy actress Katherine Heigel.

"While slightly safer than last year, searching for top celebrities continues to generate risky results," said Paula Greve, director of web security research at McAfee.

"Consumers should be particularly aware of malicious content hiding in 'tiny' places like shortened URLs that can spread virally in social networking sites, or through e-mails and text messages from friends."

McAfee said searching for tennis stars was safer this year compared to previous years as players Maria Sharapova and Andy Roddick, who came in at 13 and 14, respectively, last year have dropped to 44 and 56 this year. Furthermore, despite making headlines for his behaviour and departure from 'Two and a half men' Charlie Sheen has not been classified as a 'dangerous' celebrity, making 59 with less than three percent of searches for him yielding risky results.

"Hot movies and TV shows, awards and industry accolades seem to be more of a factor than headline-grabbing activity," said Greve.

"Still, searching for any celebrity can bring up risky sites and the public should use caution by not clicking on any page that looks suspicious."
