As fans of “Project Runway” know, one day you’re in, the next day you’re out.

This year Heidi Klum’s in and Cameron Diaz is out – at least if you’re looking at the list of the most dangerous celebrities in cyberspace, just-released by Internet security firm McAfee.

Klum, the former Victoria’s Secret model and current producer of “Project Runway” moved up from No. 10 on last year’s list to No. 1 today, replacing Diaz as the most dangerous celebrity in cyberspace. Searching for Klum results in a nearly one in 10 chance of landing on a risky site, McAfee said.

Fans searching for Klum screensavers, pictures and downloads are at risk of running into online threats such as viruses and malware designed to steal their personal information.

Cameron Diaz fell to second place this year, followed by Piers Morgan – a new addition to the top 10 list and the most dangerous male celebrity in cyberspace.

While slightly safer than last year, searching for top celebrities continues to generate risky results, as Paula Greve, director of Web security research at McAfee says:

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.”

Movie stars and models top the most dangerous list this year, while singers and sports stars are among the safest.
