Ciao.
Scarica ed installa MalwareBytes:
clicca qui per il download : http://www.aiutamici.com/software?id=80346
Prima di fare la scansione AGGIORNALO. (è molto importante)
Esegui una scansione completa del sistema.
Elimina quello che trova.
Posta il log.

Poi:
Scarica SYSTEM SCAN

scaricalo sul desktop
http://www.suspectfile.com/systemscan
Aprilo ed assicurati che tutte le opzioni siano spuntate, clicca su "Scan Now"
Finita la scansione verranno rilasciati (sempre sul desktop all'interno della cartella suspectfile) due file.
Collegati ad internet e vai alla pagina WikiSend: http://www.wikisend.com/
Clicca sul bottone "Sfoglia"
Seleziona il file appena salvato
Clicca su Upload file
Dopo qualche secondo, vieni spostato su una nuova pagina con il link in diversi formati:
Download Link / Forum Link
Seleziona Forum Link, copialo e incollalo in un nuovo messaggio per il forum.
Ricordati d'effettuare la scansione senza connessione attiva e con l'antivirus disabilitato salvo poi riattivarlo a scansione terminata.

NB:
la durata della scansione può risultare lunga, potrebbe addirittura sembrare che il programma non stia lavorando, non preoccuparti non è così.
SystemScan viene riconosciuto, erroneamente, da alcuni antivirus come infetto.

il log sopra è mio.

Scusate ma non so che fare? Qualcuno sa dirmelo? Grazie

Grazie proverò, ma vorrei anche sapere perchè non si apre systemscan.

Neutral Controllate se conoscete il sito web altrimenti eliminatelo (Fix). Oggetti ActiveX sconosciuti oppure oggetti ActiveX provenienti da siti web sconosciuti devono sempre essere eliminati. Se il nome dell'oggetto ActiveX o dell'indirizzo (URL) contiene le parole 'dialer', 'casino', 'free plugin' ecc, deve essere immediatamente cancellato (pulsante Fix di HijackThis)!
