Starter application and autorun file won't go away

I've got a SanDisk memory stick and I've used it for a couple of years and have had no trouble but recently 2 files (autorun and starter) have come up and I've tried to delete them and it wouldn't work, so I tried to open starter application but nothing happened.

Does anyone know how remove them?


You can always format the SD :)

another choice is to disable AUTORUN on you system
