Wireless users not immune to computer viruses (phillyBurbs.com)

There have been two major viruses affecting handheld electronic devices in the last six months. The most recent, known as 'skulls,'' replaces every application icon with a picture of a skull and crossbones. It also kills applications, such as the address book for a smart phone.
Security experts say you can prevent many infections just by using your head. The first major virus affecting handheld electronic devices, known as "cabir,'' spread only when smart phone users pressed "yes" when asked whether they wanted to accept a message from an unidentified device.
