Io ho individuato queste 3 voci da fixare:

O2 - BHO: (no name) - {7E853D72-626A-48EC-A868-BA8D5E23E045} - (no file)
O15 - Trusted Zone: *.whataboutadog.com
O15 - Trusted Zone: *.whataboutarabit.com

Basta fixarle o devo fare altro? Non so cosa sia la Trusded Zone!
Grazie 1000

per quanto riguarda la prima, la puoi togliere se vuoi. è inutile

per ciò che riguarda le altre la Trusted Zone è una sezione del registro dove vengono salvati alcuni indirizzi web, che appunto sono "fidati". di per sè non rappresentano un problema, ma comunque in questo caso, quei due siti sono aggiunti dal trojan zonebak (alias Istant Access o AWF)

Scarica systemscan, estrailo, avvialo, metti la spunta a tutte le voci e premi "Scan". poi vai su www.easy-share.com e metti lì il suo log (che trovi in C:\suspectfile\report.txt). poi dacci il link per scaricarlo (solo quello per scaricarlo, non quello per eliminarlo dal sito di hosting)
