On top of this, siremi, can we get confirmation that changing the password actually spoils any current password attempts?
Changing the password will take away the admin access others have on you, so they can't bounce you or access your data.
It is VERY important to change password after you upgrade your Firewall or Password Protect, because the hackers that cracked you have to crack again and they may not have the software to match your defenses, if witch case they have to upgrade the attack software too.
