<<<... While the risk of a cell phone getting infected is still relatively small, thousands of phones have seen problems. "Although the first problems were already quite extensive and appeared all over the world, current smartphones from the largest device makers, particularly Nokia, have got rid of these problems," said F-Secure's Hypponen. Almost three out of four users were concerned about the safety of using new mobile services, showed a survey of 2,000 cell phone users, commissioned by McAfee, and unveiled this week at the Mobile World Congress in Barcelona. "Concerns about specific mobile security risks or ... reliability of services is a crucial issue for operators, particularly in mature markets," Victor Kouznetsov, senior vice president at McAfee's mobile unit, said in a statement. Mobile service providers are increasingly betting on new data services when looking for growth in mature markets where call prices are falling. "Consumer fears are growing in tandem with increased mobile functionality," Kouznetsov said, adding this puts at risk the potential revenue from new services. One in seven global mobile users have already been exposed to mobile viruses, either directly or they know someone whose phone has been infected, McAfee's study showed. Since the first mobile virus appeared in 2004 the number of different viruses, worms or other types of malware has reached 395, F-Secure said, adding that the number of malware has increased only slightly in the last 12 months
