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 gli eventuali file infetti trovati.
Posta il log.

Poi:
Disistalla Avast! (è obsoleto)
Per disistallare Avast!:
Cessane l'esecuzione dalla Tray bar. (vicino all'orologio)
Scarica questo Tooll specifico sul Desktop:
http://files.avast.com/files/eng/aswclear.exe
Lo si deve eseguire in Modalità provvisoria.
Ecco la pagina con le istruzioni:
http://www.avast.com/eng/avast-uninstall-utility.html
Riavvia in Modalità normale.

Installa l'ultima versione:
http://www.aiutamici.com/software?ID=80367
Fai una scansione per vedere se rileva qualcosa.
