Palm Handheld Viruses: A Significant Threat?

Palm software is distributed as a serialized 'PRC' file of the application which can be stored on the user's local file-server/workstation. When the handheld and the local file-server/workstation are synchronized the PIIC file is installed as an executable on the handheld. A Palm virus spread in this way will have limited success: following initial infection, subsequent spread to other programs is generally limited to the handheld unit alone. Once a program is infected (on the handheld) it must uploaded to the user's workstation/file server and distributed from there before it can become a threat to other handheld units.
