J.B. fans beware – Jessica Biel has been named the most dangerous celebrity on the internet.

According to online security company McAfee Inc., fans who google the former 7th Heaven actress are more likely to end up falling victim to spyware and virus threats on their PCs than other celebrity, and have a one-in-five chance of ending up at a site that can damage their computer.

“Cybercriminals are star watchers, too. They latch onto popular celebrities to encourage the download of malicious software in disguise.”

Brad Pitt was branded the web’s most dangerous celeb in the same poll last year.

Other “dangerous” stars include R&B star Beyonce Knowles, actress Jennifer Aniston, NFL star Tom Brady, and actress/singer Jessica Simpson. McAfee noted President Barack Obama and First Lady Michelle Obama are “safe searches,” ranking No. 34 and No. 39, respectively.
