No need to be sorry, your right about system32, the rest go to contentIE5, and when "Norton antivirus" cant delete or fix some files they always lead to the contentIE5 folder, And any addware or spyware will lead also to this folder. ContentIE5 stores everything and every place you been on the internet, along with images and anything you downloaded. Believe me, its all there :) Take a look if your using XP.... x
