grazie

Per maggior visione i log di Hijack vanno messi nel forum Sicurezza virus.
Per il primo problema disattiva il salvaschermo e vedi se l'errore si ripete,inoltre disinstalla Adobe Shockwave ,dai una ripulita con Ccleaner ai file ed al registro,riavvia il pc e reinstalla Shockwave.
Per il secondo problema forse hai preso un virus(probabilmente da pen drive infetta),aspetta il parere di un esperto.
Hai installato qualcosa ultimamente?

grazie x aver spostato il mio post in sicurezza virus.

grazie provvedo subito

...sarà il caso ke scarichi e installi spyware terminator visto ke non ho 1 antispy in tempo reale? o c'è 1 altro antispyware migliore?

ok grazie. lo kiedevo xkè nel sito ho cmq letto ke gli antivirus free hanno dei limiti nel controllo degli spy e sarebbe meglio ogni tanto dare 1 passatina + approfondita con altro software (tipo clamwin)
