Carissimi Amici
Sapevo che prima o poi avrei avuto bisogno del vostro preziosissimo aiuto!
Da qualche tempo il computer è lento e presenta qualche bizzarria (es. si spegne e si riaccende). Inoltre a volte non consente gli aggiornamenti automatici di Clamwin e non consente le scansioni online.

Ho provato (seguendo tutti i vostri suggerimenti)a farlo analizzare da Clamwin che,arrivato a C\ Windows\DRIVER CACHE\i386\sp2.cab:[.] si blocca e blocca tutto, tanto che devo spegnere manualmente. Clamwin l'ho avviato più volte e prima di giungere al blocco, una volta mi ha segnalato in rosso e rimosso un W32MTX. Allora ho utilizzato Virilt che nella scansione del registro mi ha trovato un Trojan.win32.resurrector.A che però si ripresentava a tutte le nuove accensioni. Manualmente allora ho rimosso dal registro la stringa mostrata da Virilt
{3B177BCE-B599-4ABD-BECE-B57EE18187FA}. Dopo la rimozione di questa stringa il problema non c'è più, ma rimane quello del blocco aggiornamenti degli antivirus e antispy.
Avast in modalità normale non si blocca più e non trova nulla, mentre avviato in modalità provvisoria non fa comparire l'interfaccia utente, nè mi consente di avviarlo in alcun modo. Tutti gli altri programmi di analisi (spybot, virilt, clamwin, ad-aware SE personal, Firelite) anche avviati in modalità provvisoria a un tratto si bloccano e mi costringono allo spegnimento manuale del PC.
Come da voi consigliato, per ultimo ho utilizzato Hijackthis e questo è il responso.
Cari saluti e grazie infinite per l'aiuto :-)). Framy (Mteresa)
