Eliminato i due file infetti!. Adesso cosa mi consigliate di fare?
Grazie mille!

Disattiva il Ripristino configurazione sistema.
Riavvia il pc.
Crea un punto di ripristino
Se il pc non presenta problemi, direi di fermarci qui.

Purtroppo, non c'ero io fra la sedia e la tastiera, del tuo pc.
Per cui, non lo posso sapere.

No, non lo noto.
Segnami quali errori.

Ah non lo sò perchè nel tuo video compaiano detti errori.
Nel mio, non ci sono gli errori che descrivi tu.

Prova a cambiare browser .
Prova con IE, oppure con Firefox.

GRAZIE DI TUTTO.
