Prima che mi arrivasse la risposta di alfonso avevo comunque scaricato la Patch Microsoft 835732 (Sasser) e riscaricato (e fatto girare) da aiutiamoci la nuova versione di Adware (io ne avevo una vecchia) e controllando il registro di configurazione non avevo nessun file che cominciava con ysb. Quindi forse il problema si è già risolto. Vi sarei molto grata se voleste analizzarre il mio log lo stesso.
Grazie a tutti e buona domenica
Ecco il log
