Ciao Amici,
ho un problema con IE7.
Si chiude dopo pochi secondi che lo apro. Ho fatto un poì di scansioni con vari programmi ma ancora nulla.
Vi allego il file di HijackThis così magari riuscite ad aiutarmi:

Non sono un esperto ma ho riscontrato anch io questi problemi tempo fa. Credo che ti sia beccato un virus particolare di nome winupgro. Per vedere se ce l' hai apri il task manager e sulla sezione processi controlla che non ci sia un processo con il nome winupgro o simile in esecuzione. Se c'è, non è possibile rimuoverlo. Dovresti formattare tutto e reinstallare il sistema.
