Ciao ,
mi dispiace darti brutte notizie , ma anche tu sei affetto da una variante del rootkit linkoptmizer ...

Come prima cosa devi assolutamente aggiornare il tuo sistema , compreso SP2 e Internet Explorer .

Poi:
- vai in questa pagina -> http://steven.altervista.org/files/antirootkit.html
- Scarica ed esegui uno scan con l'ultimo tool presente nella lista
- Postaci il log della scansione

Poi per conoscere meglio con chi hai a che fare , dai un occhiata a questa guida ->http://steven.altervista.org/files/rootkit.html
