Iconian software transmission
The Iconian software transmission was an information transfer developed by the ancient Iconian civilization. The software used a small probe that uploaded an operating system into the target's computer system. Once there, the program began rewriting the software of the destination computer, presumably in order to facilitate communication. However, if the operating system of the target is too different from the Iconian one, they will clash, causing the vessel and its systems to malfunction and possibly suffer catastrophic consequences.

In 2365, the  discovered the Iconian homeworld in the Romulan Neutral Zone, and was subsequently infected by the Iconian probe. The Yamato was later destroyed by the program when it caused an uncontrolled release of antimatter into the Yamatos warp core. The program spread to both the  and the Haakona when they downloaded the Yamatos logs. The Enterprise-D's Chief Engineer, Lieutenant Geordi La Forge, discovered that the program could be purged by shutting down all ship's systems, erasing the infected areas, and then rebooting from the computer core's protected memory. This technique was discovered when Lieutenant Commander Data, an android who had also been infected by the program, appeared to die, but reawakened moments later, as his systems had automatically restored his programming to normal.
