Cabir Mobile Virus

The first "concept virus" developed specifically for wireless devices was discovered on June 2004.  The worm, dubbed Cabir, was designed to propagate via mobile networks and infect smartphones running the Symbian OS -- although other operating systems could be affected by the virus. Cabir was detected Kaspersky Labs.

Update September 2004: Finnish mobile phone manufacturer Nokia will offer mobile anti-virus software through F-Secure as one of the features in its new Nokia 6670 smartphone.  The Symbian OS (operating system) smart phones will provide on-device protection, similar to anti-virus protection programs for PCs, with automatic over-the-air anti-virus updates for a monthly fee.  The software will not come loaded into the device, but can be downloaded from the F-Secure website, according to Nokia spokesperson.
