da qualche giorno mi sono accorto che dal mio PC partono mail a indirizzi sconosciuti con allegati file contenenti virus. L'antivirus aziendale (OfficeScan di Trend Micro) non ha trovato niente e per il resto il pc funziona bene. allego il log di Hijackthis per vs analisi e suggerimenti. Grazie, Vik
