The virus itself does not have cells, the formation of new viruses takes place in the infected host cell. In making this application, there is also how the virus forms and in understanding it is not difficult for users to understand and all those who have used this application in biology learning media, especially in the field of viral microbes. With this application, participants can learn all the general theories that cover viruses. This learning method uses a deskstop base system in visual slides using clear Indonesian so that participants can receive messages and theories properly and easily. Sources of information are obtained from multimedia data testing of this system using a functionality test which is carried out 7 times. The test results from the system found no errors. User testing was carried out by means of a questionnaire with 16 users for 4 consecutive days. And the application is proven to run well.
