answer:It took some filtering to google an answer, but that is Windows malware. Do you dual-boot or otherwise expose these drives to windows? if not then you may have somehow encountered something that can spread through ****. In any case I would make sure to clean them all up (make sure it’s not running) and be sure to delete your .**** folder since it might be compromised. If your drives do get exposed to Windows it’s time to run some cleanup utils there. (maybe Ad-aware, Spybot search&destroy, or whatever the current favorite is) and be sure (from Linux) to clean off all your flash drives, externals, memory cards, etc.
