Ciao R16
grazie per la risposta,
non ho trovato la riga che mi dici di fissare
F2 - REG:system.ini: Shell=...........sembra sparita
il pc si avvia ancora in provvisoria con rete
e tutte le prove che mi hai descritto le ho fatte tutte ieri senza risultati
(Malware e ripristino ad una data antecedente )
explorer.exe.......dovrebbe esserci, ora sto usando il pc in questione
e riesco a collegarmi a internet
altre prove che ho fatto
disinstallato AVG versione completa regolarmente abbonato
disinstallato SP3 ed ora diversi programmi non mi funzionano più
e non riesco neppure a fare l'aggiornamento da Windows Update perchè in
modalità provvisoria
questa che vedi sotto è la situazione attuale
grazie
Daniele
