What it does

In IE, there is a"safe mode", by default it must be turned on, but you installed certain banks the control they will put it off, the purpose is to the user experience, do so after you use online banking when it is no longer required and then confirm the loading control, more important is that this operation is permanent.

This reminds me of 1 4 years of a vulnerability, through the kill IE 3 - 1 1: A

By the previous step to obtain the address using the first vulnerability is calculated"safe mode"address.
