Hai notato che c'è una procedura da seguire per la rimozione dei malware? E' scritta in un post in rilievo nel forum: http://forum.html.it/forum/showthrea...hreadid=811189

Per quanto riguarda il log. Riavvia in modalità provvisoria dopo aver disabilitato il ripristino di configurazione. Con tutte le applicazioni chiuse e disconnesso da Internet, avvia HijackThis, seleziona queste voci e premi FIX:

O4 - HKLM\..\Run: [explorer] C:\WINDOWS\system32\scif\explorer.exe
O4 - HKLM\..\Run: [winlog] winlog.exe
O4 - HKLM\..\RunServices: [winlog] winlog.exe

Prima di eliminare i file explorer.exe (in C:\WINDOWS\system32\scif\) e Winlog.exe (in C:\WINDOWS\system32) mandali per favore a suspectfile.tk per l'analisi. Li elimini in un secondo tempo, quando ti arriva la conferma che sono infetti.

PS: forse per trovarli dovrai abilitare la visualizzazione dei file nascosti e di sistema

Ciao
