Buonasera.

Da questa mattina il mio p.c. sul quale è installato il s.o. windows xp sp2 licenziato, impedisce:

- all'antivirus di funzionare (mcafee)
- al windows defender di funzionare
- non mi consente più di installare nessun programma
- non mi consente di scaricare gli aggiornamenti di windows update.

Seguendo le discussioni in rilievo, ecco il logi di hijackthis:
