Da qulche giorno non riesco più a fissare la mia pagina iniziale,su strumenti-opzioni digito il link della mia pagina iniziale(www.virgilio.it) e scelgo"mostra pagina iniziale",quando riaccendo il computers mi trovo come pagina iniziale l'ultima pagina visitata(quando va bene)altre volte un sito di ricerca che non ricordo.
Ultimamente ho installato"Pc Speed Maximizer Pro" mi sembra che dopo siano inziati i problemi.
Mi potete aiutare?Ringrazio anticipatamente.
Questo il mio log:
