it says its unavailable and might be on a different hardrive i only have 1 hardrive..the only reason why im asking is because i downloaded a virus off of lime wire and i know its in a specific file its in my share folder from lime wire and its from a song i downloaded the band name is Mighty Boss Tones...how might i get rid of this? everytime i try and delete the folder it says a critical error has cured and needs to shut down before i can delete it and my virus scanner i downloaded finds it but also says encountered a fatal error and needs to close before it can get ri of it so i don't even have the option of deleting it or quarenteening it. what can i do?

(my virus/spyware/hacker/ are all updated today and ran all searches again and still the same thing)
