I did run CCleaner after unistalling Akamai along with a lot of dead wood on my pc. Now the only reference to Akamai is the Control panel entry. When I attempted to open this file I received an error notice "Application not found". I guess it's not a problem with not being able to be opened; It's like a link to a program that has been removed.

Know if there is a proper way of removing control Panel items or will the old delete button work?
