Ciao, probabilmente in avvio si blocca perchè hai troppi programmi che si caricano all'avvio.
Avvia hijackthis, metti la spunta alle voci che andrò ad elencarti e con tutte le applicazioni chiuse e disconnesso da Internet,premi su "fix checked ":



Disinstalla emsisoft anti-malware e msn toolbar (hai già Avast!).

Riavvia il sistema e:
Scarica ed installa MalwareBytes:
http://software.aiutamici.com/software?ID=80346
Prima di fare la scansione AGGIORNALO. (è molto importante)
Esegui una scansione completa del sistema.
Elimina gli eventuali file infetti trovati

Il log, postalo con questo servizio hosting:

Elimina gli eventuali file infetti trovati

Ciao Cbbusto, scusa per l'intromissione.

Un saluto.

Francesco amato

Ciao a frascescoamato ed a cbbusto,
non ho messo in atto quanto suggerito da francesco ma ho fatto la scansione con Malwarebytes e vi posto il file log.
Da questa scansione si evince che il Pc è immune da Malware.
In giornata eseguirò i consigli di francesco.

Consiglio, quando aggiungi nuovi programmi, non installare mai le toolbar, queste spesso creano conflitti e rallentamenti, tieni solo quella del motore di ricerca.

Fai una pulizia con Ccleaner compreso il Registro, per il registro spunta tutte le voci.
Vedo che hai installato Todo Backup, hai fatto l'immagine del sistema ? molto utile in caso di problemi.
Dopo queste operazioni se tutto è a posto avremmo terminato, fai sapere. Ciao

Ciao Patton, io e cbbusto siamo felici che il PC ora vada bene.
Suggerimento; disinstalla emsisoft antimalware, visto che hai già Avast.

Per il resto, tutto ok.

Ciao!
