problema con Explorer.EXE

[zolf]

Salve a tutti!
Da un paio di giorni sto riscontrando un problema con il mio pc... Quando apro qualche cartella sull hard disk (es. Documenti, Video, Foto,...) mi appare una finestra di errore: "Explorer.EXE - è stato rilevato un errore. L'applicazione verrà chiusa", con in basso i soliti tasti "invia segnalazione" e "non inviare".
Se scelgo di non inviare il desktop scompare per un paio di secondi per poi riapparire come se niente fosse, ma cmq mi rimane impedito l'accesso a quelle cartelle là... Sono disperato perchè è un problema fastidioso e riguarda proprio le cartelle che utilizzo di più. Si può fare qualcosa che non sia la formattazione?

In modalità provvisoria ho fatto più scansioni con: Spybot, Malwarebytes e AVG opportunamente aggiornati.

Grazie a tutti!

Ciao e benvenuto su Forumzone.
 
Cominciamo col fixare questo log:
R1 - HKCU\Software\Microsoft\Internet Explorer\Main,Search Bar = http://it.rd.yahoo.com/customize/yco.../info/ie6.html
 
Hai disattivato il ripristino configurazione di sistema prima di fare la scansione in provvisoria?
 
AVG, è la versione gratuita?
 
 Se si, al suo posto ti consiglio di usare Avira, ha una percentuale di individuazione virus maggiore di AVG.

zolf, hai risolto?
