Posto il Log di Hijack, vedete qualcosa di sospetto?
Proprio ora mi è ricomparso il messaggio di avvisso di Flash, eccolo:

-----
Adobe Flash Player has stopped a potentially unsafe operation
The following local application on your computer or network

null

is trying to communicate with this Internet-enebled location:

tigersavings-a.akamaihd.net

To let this application communicate with the Internet, click Settings. You must restart the application after changing you setting
----

Grazie
Alex
