Il log é parzialmente pulito, devi disinstallare Download Accelerator (DAP)

poi devi collegarti al Windows update e scaricare gli aggiornamenti sulla sicurezza, inoltre devi installare un Firewall.

Comunque non ricordo il tuo problema, rinfrescami la memoria.

Collaboratore Aiutamici

Grazie Alfonso; avevo chiesto aiuto con il mio intervento del 22.2.2005 all'argomento "difficoltà di connessione ADSL"; praticamente non mi connettevo più a molti siti, ovvero visualizzavo in modo incompleto le pagine.
Ho seguito il tuo consiglio di eliminare il download accelerator plus, ed adesso mi sembra che sia tutto a posto. Mi sono ricordato che i guai sono cominciati quando ho sostituito col DAP la precedente versione di acceleratore.
Nel mio PC c'erano e ci sono tutt'ora l'Avast e l'antidialer digisoft.

Qualche domanda:
- come hai fatto a capire che era il DAP?.
- è consigliabile usare anche con l'adsl un acceleratore? e quale?.

Grazie di tutto ed a risentirci.
