Actress Jessica Biel has overtaken Brad Pitt as the most dangerous celebrity to search in cyberspace, according to Internet security company McAfee Inc.

For the third consecutive year, McAfee surveyed which A-list celebrity was the riskiest to track on the Internet after Pitt topped the list last year and Paris Hilton came in first in 2007.

Biel, 27, who shot to fame in the TV show "7th Heaven" and most recently starred in "Easy Virtue," was deemed the most dangerous, with fans having a one-in-five chance of landing at a website that has tested positive for online threats, such as spyware, adware, spam, phishing, and viruses.

"Cybercriminals are star watchers too - they latch onto popular celebrities to encourage the download of malicious software in disguise," McAfee's Jeff Green said in a statement.

"Consumers' obsession with celebrity news and culture is harmless in theory, but one bad download can cause a lot of damage to a computer."

"Every day, cybercriminals use celebrities' names and images, like Kim Kardashian and Rihanna, to lure surfers searching for the latest stories, screen savers and ringtones to sites offering free downloads laden with malware," the statement added.
