Salve a tutti, e buone ferie, avrei bisogno del vostro aiuto, ho un rallentamento generale di tutte le funzioni di internet.
Spero che con il Log. si possa risolvere.
Il mio computer è un portatile Acer Aspire 5315 con Windows Vista.
Grazie anticipato.
Massimo

Ciao.
Il pc è infetto da adware, e dirottatori browser vari.
Segui le indicazioni di questa guida:
http://forum.aiutamici.com/yaf_postst90814_Guida-per-eliminare-le-pagine-pubblicitarie-SOLO-LETTURA.aspx
Posta i log indicati nelle modalità descritte a fine link.

Avvia OTL.

Sotto "Custom Scans\Fixes" copia-incolla questo codice:




Clicca sul pulsante RUN FIX.
Lascia fare la scansione senza interferire.
Posta il log che rilascia.

Dimmi se riscontri ancora problemi.

Cestina JRT che hai sul desktop.

Apri OTL e clicca su CleanUP.
Si disinstallerà OTL.
Ti chiederà il riavvio del pc: acconsenti.

Al riavvio fai una pulizia con CCleaner. (registro compreso)

Sempre con CCleaner:
Apri CCleaner.
Clicca su "Strumenti".
Clicca su "Ripristino Sistema"
Seleziona TUTTI i punti di ripristino e poi clicca "Rimuovi".

N.B:
Il punto segnalato in grigio (il primo) non lo puoi eliminare per motivi di sicurezza.

Se il pc funziona bene e non riscontri problemi, abbiamo concluso.
Ciao.
