monsee:Ti ringrazio per il suggerimento e vedrò di provare,rimango comunque abbastanza scettico, in quanto utilizzando il programma Ad-Remove Master questi non lo trova"evereshome200.exe, e di conseguenza non lo può eliminare.
Comunque proverò a seguire il tuo suggerimento e ti farò sapere, per il momento ti ringrazio.

ALFONSO/monsee:Ringrazio per il suggerimento do monsee perchè non sò come ma ha funzionato(con il solo scandisk)sul disco C: e non sul F: dove era postata l'icona.
Comunque Alfonso siccome conosco da parecchio la Tua preparazione,Ti invio il Log per eventuali pulizie.Grazie
