We have just setup a new TMG forefront server and since I presume some change was made, we are all getting the following message when trying to access legit secure sites such as the bank sites.

"To help protect your security, Internet explorer has blocked this website from displaying the content with security certificate errors. Click here for options."

You can show blocked content but is is TMG that is causing this issue?

I assume this is IE? did u try changing the security settings?

first give this a try

tools->internet options->security tab->internet->custom level_>find display mixed content and set to enable

or if running on trusted sites

tools->internet options->security tab->trusted-> click on sites then add your websites

im not too familiar with forefront but is there a security wizard?

I was reading this and it talks about https inspection. is this something you have dealt with? http://www.microsoftnow.com/2010/06/blocking-skype-and-other-im-protocols-in-forefront-tmg.html

oh, beaten me to it :) I was searching the net trying to find solutions to your problem. Well hopefully the link given gives you some insight to https inspection. I think it needs the web access policy configuring to make it more secure.
