rallentamento pc e modem usb

[freedom06]

Ciao ragazzi, questa volta spero di non sbagliare. Ho un problema con il mio portatile. Ultimamente non riesco piu' ad accedere ad internet attraverso il mio modem usb Michelangelo. Nonostante abbia reinstallato piu' volte i driver del modem e verificato la disponibilita' della linea adsl, ad oggi non riesco a d accedere ad internet. Se provo a collegarmi con un modem analogico o con una rete gia esistente riesco a navigare ma con diversi problemi. In internet impiego una vita per aprire una pagina e si blocca in continuazione. Aiutatemi. Ecco il mio log file.

Ciao ragazzi, questa volta spero di non sbagliare.

Adesso ci siamo.

Programmi inutili da tenere in avvio

O4 - HKLM\..\Run: [QuickTime Task] "C:\Programmi\QuickTime\qttask.exe" -atboottime

O4 - Global Startup: Avvio veloce di Adobe Reader.lnk = C:\Programmi\Adobe\Acrobat 7.0\Reader\reader_sl.exe

Qui ci sono dei rimasugli di qualche dialer che avevi preso in passato, da eliminare anche queste

Di pericoloso non si vede niente, prova a fare scansioni con A2 squared o superantispyware e vedi se eliminano loro qualcosa.

Puoi eliminare virit che appesantisce il sistema per niente, anche un cambio del firewall potrebbe fare del bene visto che sygate ha ormai i suoi anni.

Fai la scansione con Kaspersky online ed allega qui il report della scansione.
Siccome un processo del modem si trova nell'esecuzione automatica potrebbe trattarsi del trojan Zonebac che infetta i file in avvio automatico.
Hai qualche altro problema con i programmi sotto la voce O4 - HKLM\..\Run?

Esegui anche questo tool per ripristinare Winsock e TCP/IP.
