Since viruses and Trojan horse programs have made transition into mobile devices, please do aware about this risk. According to the security software company, mobile phone viruses are aimed primarily at smart phones, with Symbian operating systems or ones with Windows interfaces.

"An owner of an ordinary mobile phones, who uses it mainly for telephoning, has no need to worry," said said Christoph Hardy, a spokesman for Sophos, a company that designs security software.

These new viruses like "CommWarrior," usually runs unnoticed in the background. It can send itself out as a multimedia message to numbers in the phone book. But as another (common) virus, it can only be activated if a user accepts and installs it.

Mobile phone Bluetooth connections are another major potential security problem, warns Marion Stolzenwald, a spokeswoman for Vodafone. She suggested that a Bluetooth connection should remain "invisible" or "hidden" and always reject any unexpected offer to your phone.
