Online searches for the actress have a one-in-five chance of hitting a Web site with malware, according to a McAfee report.
Through no fault of her own, actress Jessica Biel is now the most hazardous celebrity on the Internet.
Fans searching online for Biel have a one-in-five chance of hitting a Web site with malware, according to McAfee's third annual report listing Hollywood's most "dangerous" online celebrities.
In general, hunting for Hollywood's in-crowd poses a much greater threat than searching for just about anyone else. For example, President Obama and first lady Michelle Obama ranked No. 34 and No. 39, respectively.
Other unsafe celebrities near the top of the cybersecurity company's list include singer Beyonce at No. 2, former "Friends" star Jennifer Aniston at No. 3, and football hero Tom Brady, who came in at No. 4.
McAfee found that searching for photos, videos, downloads, wallpaper, and screensavers of celebrities who made the list could prove hazardous to the health of your computer.
"Cybercriminals are star watchers too--they latch onto popular celebrities to encourage the download of malicious software in disguise," Jeff Green, senior vice president of McAfee Avert Labs, said Tuesday in a statement. "Consumers' obsession with celebrity news and culture is harmless in theory, but one bad download can cause a lot of damage to a computer."
Using its SiteAdvisor technology, McAfee compiled the list by hunting for celebrity names that produced the largest number of risky sites and the highest percentage of risk.
