PROBLEMA Risorse del Computer

[teoo315]

Salve a tutti oggi ho aperto il mio pc desktop e mi sono trovato con una bella sorpresa l'icona sia quella del desktop che quella della barra dello start non funzionano e non mi aprono più la finestra. L'unico modo per visualizzare risorse del computer è tramite esplora risorse. Che cosa succede? Ho provato a fare una scansione con AVG ma non ha trovato nulla, poi ho provato anche con hijackthis e questo è il risultato:

hai provato a riavviare il processo explorer.exe???

potrebbe essersi corrotto explorer.quindi segui la procedura:


scarica explorer.rar da qui---> www.suspectfile.com/upload/files/lucass/explorer.rar
Fatto questo, apri il registro di sistema e ti porti fino a questa chiave
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

Clicca sulla cartellina gialla Winlogon, nel pannello di destra vedrai dei valori, controlla che il valore "Shell" sia Explorer.exe se non è così, modificalo, quindi selezioni Shell, tasto destro del mouse e scegli Modifica, nella casella "Dati valore" inserisci Explorer.exe e clicchi su Ok

Ora vai in C:\Windows e rinomina explorer.exe con il nome "abcde". Adesso apri explorer.rar e metti il file che c'è dentro (explorer.exe) nella cartella C:\windows.
CTRL-->ALT-->CANC vai in processi e termina il processo "EXPLORER.EXE". Adesso dovrebbero scomparire la barra e le icone sul desktop. Sempre da CTRL-->ALT-->CANC vai in applicazioni e clicca nuova operazione, e scrivi explorer.exe e premi invio. Ora vai nella cartella C:\Windows ed elimina il file abcde.
Riavvia il pc e vedi come va:ok:
