Da questa mattina ho questo problema sul mio portatile (OS: Vista).
A volte quando clicco su start mi compare un messaggio "Esplora risorse ha smesso di funzionare" poi compare il messaggio "Riavvio di esplora risorse in corso" a questo punto spariscono tutte le icone dal desktop, la barra delle applicazioni e le finestre aperte per poi ricomparire poco dopo. Il problema si è anche presentato una volta nel passaggio da una finestra all'altra.
Non che sia un grosso problema visto che si risolve subito da solo, però è fastidioso e soprattutto non è normale.
Ho postato qui temendo che il problema sia colpa di un virus, se ho sbagliato sezione mi scuso.
Se può essere utile posto il log di HijackThis.
Grazie a tutti per l'aiuto.
