According to a study by McAfee Avert Labs, Mobile security malware will triple next year. Mobile devices (smartphones in particular) are set to really get more and more popular, and the study contends that there could be over 700 bits of malicious code for mobiles out there by the end of 2006. Currently, there are only some 226. Additional problems for Mobile users are expected, including phishing attacks and adware and spyware.
A key part of the problem, apparently, is the failure of mobile device users to perceive their smart phones and PDAs as equally vulnerable to their PCs
