Mi si presentano i seguentiu problemi:
- tempo fa hp disinfettato il computer, pieno di virus, e alla fine di tutto ho dovuto mio malgrado eliminare due o tre file di sistema.
- li per li non ho notato particolari problemi ma...
- all'avvio windows segnala la mancanza di wincnfg e recycled\svchost (ma svchost lavora anche nel cestino?)
- si è creato un account utente amministratore, del quale non ho la password, e che mi impedisce di avviare regedit ("l'amministratore ha disabilitato questa funzione per l'utente in corso")
- non riesco a visualizzare le opzioni di visualizzazione di explorer (in una normale cartella, strumenti>opzioni cartella, cosi da non poter vedere i file di sistema).
- avast trova uno strano virus nella cartella "0" (nemmeno C:0, ma proprio 0), che non è altro che il virus Hurri.
Che devo fa?
Ovviamente è inutile dire che di formattare tutto non se ne parla...
