Internet Explorer tells you to contact your administrator when you try to access the IE settings?
This can happen if you use Spybot-S&D in advanced mode and you have used the Immunize feature without reading all the text.
Please start Spybot-S&D again in advanced mode (usually from the Start menu group Spybot – Search & Destroy, until you have already changed the desktop icon to advanced mode).
Select Tools in the left bar, then IE tweaks.
There you will see a group Recommended miscellaneous locks. Untick the checkboxes in front of both Lock IE… options.
You may need to close all Explorer windows, and maybe even restart Windows before these changes take place.
Hint: this lock function has been added mostly for multi-user environments in which you would not want other users of your computer to change your IE settings. If you are the only user of your computer, there is no real need to enable them.
