'module' showing at bottom of Invite Friends and in Blog Editing

When members use 'Invite Friends' it shows the module link. That needs to be removed or hidden. How, please?

Same thing in blog creation. Regular user (not a moderator) using JCE editor and both module and articles show up at bottom of editing box.

I searched the forum here but tbh, not sure how to search! module brings up too many unrelated things.

Thanks in advance for any help,

Bridgette

ps - I attached 2 images to show what I'm asking about .
