Salve, nel mio pc si sono infilate delle inutilità, ho lanciato una scansione con MBAM - Adwcleaner e JRT.
Il risultato è qui: wikisend.com/download/608136/AntiAdware.txt
Mi dite se è rimasto qualcosa o no.

Grazie.

Dai log dei vari programmi si vede tutto quello che è stato eliminato, è stata fatta una bella pulizia, quello che è rimasto non si vede, se non hai problemi va bene così, altrimenti fai una scansione con HijackThis e posta il log.
Questo è sempre il PC dove avevi il problema con Freemake e il NetFramework ?

Chiedo scusa ma sono costretto a riportare qui il file di log di HT, dato che Wikisend non ne vuole sapere di caricarlo.

Eccolo:

Vorrei dire che lo faccio sempre ma sai com'è, o vai di fretta o sei un po distratto... e i furbetti salgono a bordo.

Grazie Cbbusto.

Grazie per la segnalazione Giza.
