Salve a tutti sono abbastanza nuovo in questo forum.
Da qualche giorno che ho un problema con un trojan segnalato dal mio antivirus AVAST!.
Ogni volta che accendo il pc, AVAST! mi avvisa di un trojan e mi invita a cancellarlo, cosa che faccio puntualmente, ma al mio riavvio del sistema mi compare nuovamente ed avast mi rinvita sempre a cancellarlo.
Il messaggio è il seguente:
"Win32:Small-BXP in c:Windows/new.drv.sys"

Questo comporta un abbassamento delle prestazione e ancor piu' se utilizzo il browser explorer e cerco qualcosa con google mi compaiono una serie di link(fino a qui tutto regolare) ma se ci clicco mi porta sempre alla solita pagina "asearchfor".
Potete aiutarmi? Grazie

Ciao,
Scarica HijackThis, decomprimilo in una cartella tutta sua non temporanea (ad esempio mettilo in C:\HijackThis).
Avvialo e premi Do a system scan and save a log file, ti si aprirà una finestra di notepad con il risultato della scansione, copia e incolla qua il suo contenuto.
