Problema virus su PenDrive autorun.inf e "stvar.exe"

[pcg4m3s]

il mio problema è il seguente.
quando inserisco un pendrive nel computer, viene creato in esso un file autorun.inf ed una cartella "jedna" che contiene un file "stvar.exe".
il che vuol dire che deve esserci un virus nel computer creando questi file nei pendrive in modo da infettare tutti i computer ai quali poi vengono inseriti i pendrive (infatti crea un autorun). io riesco ad eliminare questi file creati nei pendrive su linux ma quando rimetto un pendrive su windows me li ricrea di nuovo e così via...
le ho provate tutte. ho fatto scansioni con spybot search e destroy, avira, HouseCall, hijackthis... ma nessuno trova nulla. il file autorun.inf non me lo fa aprire con un editor di testo per vedere che c'è scritto. dice "can not open file G:\autorun.inf".
formattare per questo motivo mi sembra eccessivo... qualcuno di voi conosce una soluzione?

alla fine sono riuscito a leggere il contenuto del file autorun.inf grazie al programmino "Autorun Eater".
