Looking for Beyonce? watch out risky cybercriminals!

An internet security firm has dubbed the actor and singer the most dangerous celebrities to search for on the Internet because cybercriminals use their names to lure victims.

California-based McAfee Inc. said fans searching for information and pictures of Pitt, or downloads, wallpaper and screen savers, have an 18 percent chance of having their PCs infected with a virus, spyware, spam, phishing and adware.

"Cybercriminals employ numerous methods, yet one of the simplest but most effective ways is to trick consumers into infecting themselves by capitalizing on Americans' interest in celebrity gossip," explained Jeff Green, senior vice president of McAfee's Product Development & Avert Labs.

"Tapping into current events, pop culture or commonly browsed sites is an easy way to achieve this," he added in a statement.

Web surfers looking for celebrity gossip, screen savers and ringtones are often directed to fake Internet sites that look legitimate but pose a risk to the security of their computers, according to the company.
