Ciao ,
si il tuo log è pulito , a parte questa voce aggiuntasi nella trusted zone che dovrebbe redirigere verso siti poco affidabili...
Quindi fai cosi:
- Scarica lo script per riparare la trusted zone
http://www.mvps.org/winhelp2002/DelDomains.inf (---)(tasto destro sul link e salvalo sul desktop)
Una volta salvato , cliccaci con il tasto destro sopra e seleziona "installa"

Adesso controlla il log e se la voce 015 risulta ancora presente , metti la sua relativa spunta e clicca su <b>fix checked</b>

Dovresti installare anche un firewall diverso da quello di windows -> http://www.aiutamici.com/software/descrizione.asp?CodSw=56
