problema con il browser IE

[frelma]

ciao a tutti,
ho alcuni problemi forse correlati tra loro. Premetto che non sono un esperto di Windows e chiedo scusa se scriverò strafalcioni.
Possiedo un portatile con XP SP3 e mi collego ad internet tramite chiavetta USB.
Da qualche giorno non riesco ad utilizzare il browser Internet Explorer (versione 7): la finestra si apre ma non succede niente. Ho provato ad installare IE8 ma il risultato non cambia: il browser si apre ma si richiude immediatamente.
Ho provato (per sostituirlo) a cancellare e/o rinominare il file iexplore.exe dal path C:\Programmi\InternetExplorer\ ma ho visto che riappare sempre dopo pochi secondi (è una funzione del S.O. oppure un virus).
Ho fatto una scansione con Spybot-S&D che mi trovato un po' di cookie e un dialer ... però il problema persiste.
Ho anche fatto girare HIJACKTHIS e COMBOFIX: purtroppo non so interpretare questi log!

Vi segnalo anche questo fatto: se installo Mozilla Firefox versione 3.x.y non riesco più a fare l'autenticazione per la connessione ad internet.
Sto partecipando a questo forum perchè ho installato una vecchia versione di Firefox la 1.5.0.1

Grazie a tutti per la vostra attenzione e per l'aiuto.

ecco il log di HJT.
Il log di COMBOFIX è di circa 19000 caratteri. Come posso metterlo a disposizione?
Grazie.

ciao
il log è sostanzialmente pulito...solo delle tracce di file mancanti probabilmente residui di disistallazioni.
fixa queste voci

poi
scarica ed istalla ccleaner e fai una puliza dei file temporanei,dei cookie e delle vecchie chiavi di registro.

scarica e istalla spybot search & destroy . aggiornalo ed esegui una scansione

scarica e istalla mbam , aggiornalo ed esegui una scansione.

facci sapere come va.

Ciao,
prima della tua risposta ho fatto un po' di pulizia con ATF-Cleaner e Trojan Remover.
Poi ho installato Spybot-Search & Destroy.
Quando ho visto i tuoi consigli ho anche fatto una passata con CCLEANER.
A quel punto sono partito con le installazioni di IE8 e Firefox 3.5.6
E adesso funziona tutto.
Credo non ci fosse un vero e proprio virus, ma un bel po' di "porcherie" qua e là e magari dei registri non proprio a posto.

1.000 Grazie
e Buon Anno a TUTTI
