Emma Watson may look like a frail English rose, but she has been labelled the most dangerous celebrity - to search for on the Internet, that is.

Watson, 22, next to be seen in teen flick Perks Of Becoming A Wallflower, is now tops on the list of famous names that cybercriminals use to lure online searchers into downloading malicious software or unwittingly exposing their personal information.

The actress has replaced Project Runway host Heidi Klum as the most dangerous star to search for online, according to tech security company McAfee.

Users searching for her have a one in eight chance of ending up on a malicious website.

Rounding out the top 10 are Jessica Biel, Eva Mendes, Selena Gomez, Halle Berry, Megan Fox, Shakira, Cameron Diaz, Salma Hayek and Sofia Vergara.
