Jessica Biel Is The Most Dangerous Celebrity Alive ... In Cyberspace

Jessica Biel In the precarious star-fan dynamic, it's often the celebrity who finds themselves in uncomfortable situations thanks to overzealous acolytes wielding camera phones and begging for autographs or bites on the neck (sorry, RPattz). But sometimes it's the fans that need to be weary of celebrities — especially on the mean streets of the World Wide Web.

Internet security company McAfee just released its third annual list of the "Most Dangerous Celebrities in Cyberspace," ranking actress Jessica Biel #1, overtaking the top spot from Brad Pitt. Searching for JT's gal pal gives surfers a one in five chance of downloading harmful materials, including viruses, on to their computers.

“Cybercriminals are star watchers too — they latch onto popular celebrities to encourage the download of malicious software in disguise,” said Jeff Green, senior vice president of McAfee’s Product Development & Avert Labs.

Not surprisingly, young Hollywood was well represented on the list with the House of Mouse holding a large number of the top spots. Disney darlings dominating the list include Miley Cyrus (#7), Ashley Tisdale (#9), Vanessa Hudgens (#17), Zac Efron (#21) and the Jonas Brothers (#23).

Other Hollywood Crush favorites rating high include "Twilight" twosome Kristen Stewart (#20) and Robert Pattinson (#30), Beyonce (#2), Megan Fox (#8; tied with, ironically enough, Angelina Jolie) and Taylor Swift (#16).

We don't want to be all doom and gloom, so just take our advice. Be careful the next time you're looking for Rob Pattinson wall paper or a Megan Fox screensaver, because your celebrity fantasy could be your laptop's worst nightmare.
