She may be known for her playful giggles and killer looks, but now movie star Cameron Diaz has become the most dangerous celebrity on the Internet.

　　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 know that people want to have screensavers of popular individuals. 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, followed by Brad Pitt, one of only two men to be listed in the top ten.

　　“Brad Pitt is historically one of the most dangerous celebrities to search on,” said Marcus. “He's always up there.”

　　Former Victoria's Secret model Adriana Lima came in sixth, followed by Jennifer Love-Hewitt and Nicole Kidman, who tied for seventh. Tom Cruise ranked eighth, and Heidi Klum and Penelope Cruz tied for ninth. Anna Paquin, the star of TV hit “True Blood”, rounded out the top ten.

　　This is the fourth time McAfee published the annual list of dangerous individuals.

　　影星卡梅隆•迪亚兹凭借她调皮的笑容和惊艳容貌为人们所熟知，而如今，她已成了网络上“最危险的名人”。

　　根据迈克菲计算机安全公司的一项调查，37岁的迪亚兹名列网络搜索最危险名人排行榜之首，茱莉亚•罗伯茨位居其后。去年的网络最危险名人杰西卡•贝尔今年跌至第三位。

　　迈克菲公司本周四发布的这项调查显示，在带有迪亚兹名字的网站中，有十分之一的网站上含有会让电脑中毒和盗取用户数据的恶意软件。迪亚兹曾出演过影片《危情谍战》。

　　迈克菲实验室网络安全负责人戴夫•马克斯说，恶意软件开发者用名人作为诱饵，引诱粉丝和崇拜者点击下载看似无害的内容，而这些内容包含着会盗取密码和其他私人信息以牟利的程序。

　　马克斯说：“他们知道人们想用名人的做屏保。他们会追踪网上的热门话题，据此制造出带病毒的内容。”

　　他说：“这属于一种’社会工程‘攻击行为。很多时候，网络罪犯会对推特或谷歌趋势进行追踪，然后据此制造病毒。很显然他们将会用新闻热点作为诱饵。”

　　超模吉赛尔•邦辰位居第四，布拉德•皮特位居其后，只有两名男性跻身排行榜前十位。

　　马克斯说：“从以往的记录来看，布拉德•皮特一直是网络搜索最危险的名人之一。他总是榜上有名。”

　　曾在“维多利亚的秘密”公司做过模特的阿德瑞娜•利玛名列第六，詹妮弗•洛芙•休伊特和妮可•基德曼并列第七。汤姆•克鲁斯名列第八，海蒂•克鲁姆和佩内洛普•克鲁兹并列第九。出演热门电视剧《真爱如血》的明星安娜•帕奎因位居第十。

　　这是迈克菲第四次发布年度网络最危险名人榜。
