A new virus affecting Symbian smart phone devices is on the loose. This virus/trojan uses the Bluetooth interface to spread itself to any unsuspecting device that it can access and tries to deposit itself to further spreading infection. 

"Upon execution, the virus searches for nearby Bluetooth devices (those which are in discoverable mode) and tries to transmit itself to any accessible ones. It also initiates a drive-wide scan for SIS-files and tries to infect them by inserting virus code directly into an SIS archive," the Kaspersky Labs warning said.

Sounds like the common cold to me.
