Ciao,
il log é pulito....dovresti aggiornare IE e sp2...
Comunque prova a fare uno scan online e vedi se viene fuori qualcosa:
BitDefender

Panda

>>>Antispyware<<<

Trend Micro

[iko75]

per sp2 ho un problema il negoziante mi ha fornito un hd con una copia clonata di OS..

[iko75]

ma se non uso ie xè lo devo aggiornare?

uso firefox come browser e thunderbird per le mail..

[fabrizius]

Si ma IE devi aggiornarlo anche se non lo usi,e poi per il windows update o per gli scan online si deve usare per forza....comunque se non puoi fare il windows update vai almeno in questa pagina e installa le ultime patch per la sicurezza,altrimenti sarai sempre vulnerabile ad attacchi di vario genere
