Avoid Searches for Cameron Diaz on the Web

Diaz, 37, is top of the list of the most dangerous celebrities to search for online, above second-placed Julia Roberts, according to computer security company McAfee, Inc. Last year's most dangerous Web celebrity, Jessica Biel, fell to third.

One in ten websites featuring the "Knight and Day" star contain malicious software intended to infect computers and steal data from users, according to research released on Thursday by McAfee.

Creators of malicious software use celebrities as lures, baiting fans and followers to click on and download seemingly innocuous content containing programs designed to steal passwords and other private information for profit, said Dave Marcus, director of security research at McAfee Labs.

They follow hot topics on the Web and create their poisonous content accordingly," Marcus said.

"This relates to a larger trend of using social engineering lures. A lot of times a cyber criminal will mine Twitter, or follow Google Trends, to poison those links. It's very clear they will use news trends to lure," he said.

Supermodel Gisele Bundchen came in at fourth.  Brad Pitt is also one of the celebs that is dangerous to randomly search for.  This is the fourth time McAfee published the annual list of dangerous individuals.
