How to disable IE Add-On from Accessing C: Drive?

Hi everyone - I just installed a security camera at home and the built-in software uses Active-X controls in IE. The software asked to install an Add-On, which I allowed, and then some other pop-up appeared (from Windows Security Center I believe) that asked if I wanted to allow IE to access the hard drive. Sadly I clicked 'Yes' and checked-off 'Never ask again', and now when a certain event happens with the security camera software, IE opens the Public folder on my C: drive.

I have searched high and low for 'the how' to fix this... I've looked in the Windows Event viewer, Windows Firewall settings for programs, Program access, IE settings, Manage Add-Ons (disabled the add-on and it still did it), I've run HiJackThis to see if any changes had occurred, and some other ideas I cannot remember right now. I am wondering if you have any advice for what I am missing. Maybe there is another setting within 'Manage Add-ons' that I missed? Maybe there is a system file somewhere I should look for, or a registry key?

Thanks for any ideas, anything will help!

 

How about trying uninstalling the camera's software and see if that removes the offending code. Then you can reinstall it with the appropriate 'safeguards' in place.
