As stated above
They actually exist as a tag on each and every folder and file they are visible on.
Thankfully windows will automatically "cascade" the settings you make at the top level to all lower levels
This means that if you change permissions on a folder the permissions changed will also apply to all folders and files contained in it, as so on down the tree.
If you find the highest level folder that the user appears on and use the remove button to completely remove the user entry, when applied this will also remove the entry from all folders and files below this.
I would first right click on the actual drive in Computer and check the permissions - removing them here will remove them from the whole drive
