Alfonso,ho fatto come mi hai detto,ma anche lanciando NAV-Adware-Spybot,non risulta niente,e solo symanteck Security Check,che mi da questi due file infetti,nel sito stesso sono indicate le operazioni da effettuare per rimuovere il primo,per il secondo,digitandolo nella riga "Cerca" mi indica che non viene riconosciuto,io per l'inglese sono negato, puoi immaginare cosa posso capire dalle loro indicazioni. Il Computers mi sembra funzioni regolarmente,non noto anomalie,di conseguenza se ci sono mi tengo i file infetti, ma di formattare non se ne parla.Comunque grazie.
