Esegui 
e grazie per avermi accettato con voi...spero di postare nella sezione giusta...comunque prima di farlo ho guardato in giro e ho letto cose discordanti per quanto riguarda il mio problema per questo ho pensato di inviare il log...
ho avviato hijackthis e facendo annalizare il risultato del log sul sito omonimo una stringa mi è sembrata strana :O4 - HKLM\..\Run: [Alcmtr] ALCMTR.EXE posto il log per cortesia potete dirmi se è tutto ok o se devo eliminare qualcosa?
grazie
