My problem resembles the one described in this post:
A mysterious French keyboard layout appeared in my keyboard layout list, but is not removable by normal means. The poster linked above identified this problem stemming from a Remote Desktop connection. Googling around, I have found other similar posts, all pointing to a remote desktop connection as the source of the problem.
However, I have not (to my knowledge) used Remote Desktop. Is it possible that this keyboard layout was added in another way? Or should I start worrying about a security breach?
If a remote desktop connection is the danger here, what steps are appropriate to diagnose and and secure my computer? I have followed on online tutorial to disable Remote Desktop connections, but I wouldn't know what else to do.
