Regsvr32 nessun nome di DLL specificato

[armando_84]

Salve,
ho un problema con il PC.
Da qualche giorno non mi si installano + gli aggiornamenti e all'apertura di explorer, ma anche all'avvio di windows mi compare una finestra con scritto Regsvr32 nessun nome di DLL specificato.
Ciò è successo in seguito ad una scansione effettuata con HijackThis dato che mi si aprivano continuamente finestre di explorer con pubblicità nonostate io uso chrome. Cmq ho effettuato scansioni in modalità provvisoria con spybot search and destroy, malwarebytes, clamwin e combofix, in modalità normale con avira e una pulita con ccleaner. ora vi allego il report di HijackThis. Grazie per l'auito.

Se copi incolli il log QUI e lo analizzi noterai tra i risultati che ci sono dei processi sospetti probabilmente riconducibili a malware (cosa frequente per eseguibili che vengono avviati dal percorso "impostazioni locali").
Fatti eventualmente aiutare in questo thread per il log in questione: http://www.hwupgrade.it/forum/showthread.php?t=937676
Successivamente ricontrolla tutto il sistema seguendo la guida alla disinfezione:
http://www.hwupgrade.it/forum/showthread.php?t=1599737

A quel punto, se il sistema risulta pulito e il problema persiste, posta nuovamente qui nella sezione Windows.

PS: evita il crossposting in futuro, ti ho cancellato il post nell'altro thread.
