Bad CC - Instructions on how to find it and how to get rid of it (including list)

Thank you for the help.
I have one quick CC question though.

To try to fix my problem I've uninstalled all my CC. Actually, I did this before late night, if it matters. Anyway, I uninstalled from the launcher as well as deleted the *.epc (3rd party CC file extension, I might have the wrong one lol) files in my DCCache folder. I also deleted my DCBackup folder. So the question is, could possible bad CC still remain? Is there anything else I have to do to clear my CC from the game? Thanks.
