I-mac is being hacked?

The Computer ‘ord38s01-in-x0e.1e100.net’ is attempting to access Goggle Chrome on your computer.

Do you want to allow this connection? Block or Allow? Of course I block it.

This appears ever so often when I open up Google Chrome. It’s a notification from Norton Internet Security. Of course I say no, but I was wondering if someone is trying to hack my computer, or trying to use my bandwidth to download games, etc? I ask that because i notice several times when i quit Chrome, it tells me a download is in progress, although I have not tried to download anything.

Thanks.

Oh, I am new here but my computer is an I-mac (mid 2010); software Yosemite 10.10.5; 21.5 inch display; processor 3.06 GHz Intel Core i3; memory 8 GB 1333 MHz DDR3;
