Ciara, Flo Rida and Bruce Springsteen have landed at the top of a new list of dangerous celebrities - as far as Internet security is concerned.

Researchers at computer security company MCAfee found Internet searches for the hitmakers, and stars like comedians Jimmy Kimmel and Chelsea Handler and Christina Aguilera are most likely to come with spyware and viruses.

Kimmel tops the new list with MCAfee experts claiming any search for his name carries a 19 per cent chance of landing on a website that has tested positive for spyware, viruses or malware.

He is closely followed by Ciara.
