Jessica Biel has been named the "most dangerous celebrity" online.

Security technology company McAfee Inc. announced Tuesday that searches for the actress are more likely to result in viruses and spyware than searches for any other celebrity.

Searchers seeking info on Biel, 27, have a 1-in-5 chance of ending up at a Web site built to damage their computer.

After Biel, in order, were Beyonce, Jennifer Aniston, Tom Brady and Jessica Simpson. President Barack Obama and first lady Michelle Obama are "safe searches," ranking No. 34 and 39.

"Cybercriminals are star watchers, too," Jeff Green, senior vice president of McAfee's product development, told The Associated Press. "They latch onto popular celebrities to encourage the download of malicious software in disguise."

Brad Pitt was named the "most dangerous celebrity" in 2008.
