Vediamo se potete aiutarmi: improvvisamente oggi mi è comparsa una finestra di AVG in cui segnalava minacce multiple, tutte indicate come trojan downloader generic 10 tlx, ma attualmente sto scansione non sta rilevando nulla mentre la prima finestra mi indicava una trentina di minacce tutte nello stesso file (uno file tra l'altro del modem). Non ho trovato alcun riferimento a quel trojan, qualche idea?
Allego copia del log di HJ: http://www.mediafire.com/?34c3tck0s0pez8k

TI POSTO IO IL " TUO " LOG .... LA PROSSIMA VOLTA LO PUOI FARE TU CON IL COPIA ED INCOLLA

Sì esatto, un amico stava visitando un sito e sono apparsi i messaggi di errore. Anche spybot dà tutto negativo.
Grazie boss.
