da premettereche prima di tutto avevo provato con il punto di ripristino e poi le scansioni con l'antivirus e l'altro ad-were (avevo disattivato il ripristino) inoltre ho provato anche con etremoved...ma nulla non funziona proprio quest'ultimo!!
grazie ancora della risposta a devo essere guidato passo passo perche sono prprio un neofita...e grazie sopra tutto del controllo dei log ciao a tutti

hai provato a cambiare collegamento? in aggiornamenti in alto a fianco aggiornamenti c'è la casellina dei server, prova a selezionarne un altro

<BLOCKQUOTE id=quote><font size=1 face="Sans Serif, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>
si mi dice sempre nessun server selezionato
<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Sans Serif, Arial, Helvetica" size=2 id=quote>

Giustappunto: prova a selezionarne uno...
