McAfee ran tests in July to identify dangerous websites, and said criminals believe the three celebrities are the perfect lures to sucker people into visiting malicious websites that can infect computers.
Once a computer is infected, all kinds of personal information can be stolen, including online banking passwords and e-mail passwords.
The McAfee Most Dangerous Celebrities study found that movie stars' names are among the more dangerous searches, whereas politians' names are safest.
This is the fourth year in a row that McAfee did this study.
Here are the top ten dangerous searches on the list:
- Cameron Diaz
- Julia Roberts
- Jessica Biel
- Gisele Bündchen
- Brad Pitt
- Adriana Lima
- Jennifer Love Hewitt, Nicole Kidman
- Tom Cruise
- Heidi Klum, Penelope Cruz
- Anna Paquin
