yaguis, That's because the virus is likely active in the RECYCLER directory on the nuvi. From there it executes itself every time the nuvi gets plugged in, hence why you see what you see every time you re-plug the nuvi in.

You need to delete the RECYCLER directory(it doesn't belong on the nuvi anyways), then do a complete and full virus and rootkit scan of your nuvi and computer with the latest signature update from Panda.

Conficker was licked some time ago so long as one kept their OS and antivirus updated.
