Ciao, ho il portatile che da un po fa le bizze, sicuramente ha qualche problema e la scansione con l'antivirus non evidenzia nulla, mi controllate il log di HijackThis per favore?
Grazie
Simonetta

Ciao simonetta, il log non presenta problemi ci sono troppi programmi in avvio che bene non fanno, la lentezza può dipendere anche da altri fattori per esempio com'è configurato il pc, quanto spazio c'è sul disco e quanta ram hai installata, comunque fai queste 2 scansioni e posta i loro log poi ci risentiamo questa sera e ti dico cosa eliminare:

Scarica Adwcleaner sul desktop:
http://general-changelog-team.fr/en/downloads/finish/20-outils-de-xplode/2-adwcleaner
Avvialo e clicca sul pulsante "Elimina".
Conferma con OK le varie finestre che ti compariranno.
Il pc si riavvierà, e uscirà il log con le eliminazioni.
Postalo qui.

Poi installa malwarebytes QUI alla fine dell'installazione togli la spunta alla voce Installa malware Pro di prova, lo devi aggiornare e fai una scansione COMPLETA non veloce
elimina quello che trova e posta il log. Ci risentiamo, ciao

In attesa del log di malwarebytes eliminiamo delle voci in HJT.

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:

Alla fine fai una pulizia con Ccleaner compreso il Registro, per il registro spunta tutte le voci.
Poi vai in C:\windows cerca la cartella Prefetch aprila ed elimina tutti il contenuto, non eliminare la cartella.
Dimmi se il pc è migliorato o se fa ancora le bizze, eventualmente dimmi di che bizze si tratta. Ciao

Simonetta ti avevo deto di eliminare tutto quello che trova malwarebytes, seleziona tutte le voci e poi clic sul pulsante in basso Rimuovi. Ciao
