Salve a tutti, imploro il vostro aiuto riguardo ad alcune anomalie che ho riscontrato:
- ogni volta che spengo il pc, mi viene chiesto di installare gli aggiornamenti (ogni volta, anche subito dopo averli installati)
- le proprietà dello sfondo del desktop non funzionano correttamente. Ad esempio, se le immagini non sono bitmap non rispettano la posizione indicata ("affiancata", "al centro").

il mio antivirus NOD32 non ha trovato nessun virus, alcuni programmi di scansione (spyware doctor, ad-aware, sysclear, malwarebytes) invece si. Dopo averne eliminato qualcuno manualmente, questi programmi non trovano più niente. Ho usato anche un programma per correggere gli errori di registro ma niente, i problemi persistono.

Ho fatto una scansione con HiJackThis, ecco il risultato:

Probabilmente gli aggiornamenti non si installano affatto, può succedere;


Prova la posizione estesa;


In effetti il log non presenta anomalie. Prova con un Ripristino configurazione di sistema.
