Dozens of attendees at the World Athletics Championships in Finland have been hit with the Cabir mobile phone virus. The Finnish Communications Regulatory Authority has issued an alert after many attendees reported incidences of the virus, which spreads by Bluetooth, finding other Symbian Series 60 phones in the area and sending a file that contains the virus. Local telecoms operator TeliaSonera has set up a special centre at the stadium to try to contain things.

"In order to prevent mobile malware from spreading at the event, we have provided some powerful security software," said Pasi Mehtonen, vice president of mobile services at TeliaSonera.

"We have already taken measures earlier this year to prevent any known viruses from infecting TeliaSonera customers through MMS messages."
