I used to have MSN Messenger installed, but I have now removed it.
However, despite running CCleaner and also manually deleting auto-complete history, when I try to log into my Medion router homepage, the drop-down menu includes auto-complete options for the two e-mail addresses I used to use for MSN Messenger. (Even though these addresses were never used for my Medion router page.)
Are there some auto-complete details that are not deleted by CCleaner, and is there any way to delete them entirely?
