Looks like it has been registered by Tucows.

akamaitech is often used by spywares mostly to serve ad contents.

I have no clue why you mentionned the FBI, it certainly has no direct link with this ip.
Your searches seem to be somewhat misleading.

Try adaware to search your computer for spywares, I am almost certain it's a spyware bundled in some "free" app you got from tucows.
