Ciao
dunque il problema è il seguente..mi son preso il virus kamsoft e annessi, ho provato a eliminarlo con kaspersky e in parte penso ci sia riuscito il problema è che ora se clicco su C o D o qualsiasi disco non me lo apre...esce il comando "apri con" ed esce una lista di programmi. Penso ci siano dei file nascosti tipo autorun.inf etc etc solo che non riesco ad attivare la visualizzazione dei file nascosti o meglio spunto il tag x visualizzare file nascosti etc etc ma senza effetto!!Come posso fare ?

Grazie ciao

ciao

prova ad andare su questa chiave

HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\Advanced

imposta a 0 (zero) il valore esadecimale "Hidden" per visualizzare i file nascosti. Riportandolo a 1 (uno) nasconderai nuovamente i file di sistema.


Per quello che hai in hjt, fixa queste chiavi inutili

scarica Malwarebytes http://www.malwarebytes.org/mbam/program/mbam-setup.exe
1) lo installi
2) lo aggiorni
3) fai una scansione scegliendo la modalità completa
4) NON eliminare per ora le ventuali minacce che rileva
5) finita la scansione seleziona il tabellino log, apri il file di testo e postalo sul forum

Attendo tue notizie (spero buone)
