Devotees to the Blade Trinity actress are more likely to end up falling victim to spyware and virus threats on their PCs while searching for information on the beauty more than any other celebrity.
According to online security company McAfee Inc., fans 'Googling' the actress have a one-in-five chance of ending up at a site that can damage their computer.
However, Biel is in good company - Hollywood heavyweight Brad Pitt was branded the most dangerous celebrity online in the same poll last year (08).
A spokesman for McAfee explains, "Cybercriminals are star watchers, too. They latch onto popular celebrities to encourage the download of malicious software in disguise."
Other 'dangerous' stars include Beyonce Knowles, Jennifer Aniston, Tom Brady and Jessica Simpson.
