ogni tanto IE8 si blocca (non risponde) senza una causa precisa apparente. Riavviandolo si ripristina normalmente....fino al blocco successivo ovviamente

ecco il log di Hjiack per un controllo

grazie....

Urca...hai l'Userinit non in regola.
F2 - REG:system.ini: UserInit=F:\Windows\system32\userinit.exe
Manca la virgola finale.
Dovrebbe essere così:
UserInit=F:\Windows\system32\userinit.exe,
Te la senti di provare a mettergliela a mano?
La chiave è questa:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
Clicca una volta su Winlogon
individua nella finestra di destra Userinit
Doppio clic su Userinit.
Sulla finestra che si apre aggiungi una virgola subito dopo exe
Così:
userinit.exe,
Conferma, e riavvia il pc.

Se non conosci questa voce, puoi eliminarla:
O4 - HKLM\..\Run: [bit4id csp store register (M)] RUNDLL32.EXE "C:\WINDOWS\system32\bit4upki-store.dll",RegisterMyPhysicalStore
Per il resto sei a posto.
Vedi se il pc continua a fare scherzi.

Ah bene.... perchè io non avevo idea di cosa fosse.
Ciao!
