Aiuto non riesco più ad accedere alle unità disco rigido

[futurama]

Salve,
Ho come sistema operativo Windows Xp,è sempre funzionato tutto correttamente ma da oggi quando vado in RISORSE DEL COMPUTER e clicco sopra all'icona del disco rigido C: o la ripartizione D: per accedere ai contenuti degli hard disk mi si apre una finestra che mi chiede con quale programma voglio aprire il file C:\ (per capirci si apre la finestra dell' "APRI CON" con la lista di tutti i programmi...) praticamente non mi riconosc più C: come una unità di disco rigido ma la riconosce invece come un file!
Come posso fare per risolvere questo problema??

Mi pare ci fosse un virus che faceva una cosa del genere. Prova a fare una scansione anche con hijackthis.

Ok, ho appena fatto la scansione con hijackthis e questo è il risultato:

Perfetto ho risolto il problema, si trattava di un virus

Sarebbe oppurtuno e utile per altri utenti che dovessero incontrare lo stesso tuo problema sapere quale virus e rimedi da te applicati.

Ciao

[futurama]

L'antivirus usato è AVAST 4.8, ho fatto la scansione in modalità provvisoria; purtroppo il nome del virus non me lo ricordo

Dovrebbe essere nel log di Avast (o event log), normalmente gli antivirus registrano tutto ciò che hanno fatto.

ma se non c'è non fa nulla... Grazie

Se ti ricapita ceca nel registro questa parola:

Poi cancella tutte le sotto-cartelle di quella chiave
