I doubt it's just a keepalive signal, because it's never done this before on my old computer. I ran netstat again, but it opened for a split second, so I did a quick Printscreen. It has me established with a(string of numbers ex.64-345-23-43).deploy.akamaitechnologies.com so I'm looking that up right now.
EDIT: Apparently it's not spyware or anything, it's a "giant webhoster, specialised in load-balanced hosting for companies so that you can everdownload (every) files at the best possible speed."
