Dopo aver scaricato un programma non propriamente "certificato" da un sito tutto sommato affidabile nel computer che utilizzo in ufficio si è insediato un programma generatore di eseguibili contenenti tutti dei cavalli di troia. Questo programma, nascosto chissà dove, non fa che generare continuamente eseguibili tipo 529782.exe (esempio) che puntualmente l'antivirus Avast intercetta, riconosce come virus Win32:Alphabet-0 (Trj) e mi fa spostare nel cestino.
Invio il log del computer infetto. Potete essere gentili da dirmi come fare per eliminare questo maledetto generatore di cavalli di troia? Grazie, jjmmy
