Welcome to the Joomla forum!

The Joomla Extensions Directory (JED) lists this extension, JCK Editor, as abandoned, meaning that the download link is broken and no support nor updated versions are available for this extension.

Just uninstall this extension. That will hopefully get rid of the banner in Administrator.

Dear Toivo Talikka,

Thank you so much for your reply.
I already uninstall this extension but till this remains all Joomla Administrator pages, only it disappear in K2 article pages.
Would you please advise how to remove this manually? Thank you Toivo again.
Regards.

Is there perhaps a K2 plugin or module for JCK Editor, which would have to be uninstalled separately?

Would you please check the attachment as I found in website as cache file for the footer injection?
Thank you.

Cache files can be removed. If the website uses caching, Joomla creates cache files when required.
