Vi posto il log di hts .....ho un accesso lentissimo e, a volte non riesco proprio ad accedere e devo interrompere forzatamente e ri accendere.
Non riesco a capire cosa possa essere.

Il log è pulito, se ti colleghi con una chiavetta i rallentamenti ed anche i blocchi sono possibili.
Pulisci la cache del browser e fai il test della connessione per controllare la velocità.
Ciao

Vedo che hai un collegamento con tim Mobile, vai QUI e trovi
Speed Check inserisci la chiavetta e fai il Test.
Se si tratta dell'avvio di XP fai una pulizia con Ccleaner compreso il registro, fai una deframmentazione del disco e poi esegui anche uno scandisk.
Scarica QUESTO programma, aprilo e clicca su
Avvia, lascia fare fino alla fine, dovrebbe correggere diversi errori di XP.

Poi Chiudi tutti i programmi e disconnesso lanci HJT e clicca sul secondo pulsante: Do a system scan only poi metti la spunta alle voci che ti indico e alla fine clic su Fix checked.
