Anti-virus vendor McAfee's Avert Labs predicts that mobile viruses will increase greatly in 2006. Mobile viruses are a relatively new concern; the first, which was a "proof of concept" virus against the popular Symbian operating system, was not seen until June, 2004. The rise of mobile viruses is tracking the increasing popularity of smart phones. Avert says that these viruses could be more damaging than desktop attacks because an overwhelming percentage of devices have no antivirus protection. The lab also says that phishing and identity theft attacks will increase next year. The company counsels users to become educated about the threats and deploy updated security software.
