in questi ultimi giorni ho notato una lentezza nelle prestazioni.
Mi controllate il Log?
Grazie

ciao Giovanni

a volte la lentezza e' dovuta anche alla mancata pulizia del tuo pc

il log e' pulito- prova ad eseguire queste pulizie

scarica http://www.aiutamici.com/software?ID=11223

In fase d’installazione togli la spunta altrimenti viene installata Yahoo Tollbar.
Avvialo e clicca su:
- Opzioni Avanzate
Togli la spunta da:
- Elimina file solo se più vecchi di 48 ore
Clicca i tasti:
- Pulizia (il primo in alto a Sinistra)
- Analizza ( Pulsante in basso Centrale)
- Avvia Pulizia (Pulsante in basso a Destra)

Usa anche http://www.atribune.org/ccount/click.php?id=1


Avvia ATFCleanercon un doppio click

seleziona la casella Select All
clicca sul pulsante Empty selected
aspetta l'avviso Done Cleaning
(se usi opera o firefox,spunta anche le loro sezioni)


Prova a fare una scansione con Malwarebytes http://www.malwarebytes.org/mbam/program/mbam-setup.exe
1) lo installi
2) lo aggiorni
3) fai una scansione scegliendo la modalità completa
4) NON eliminare per ora le ventuali minacce che rileva
5) finita la scansione seleziona il tabellino log, apri il file di testo e postalo sul forum
