Yes I believe it is a spyware program. I have 3 visits almost daily for months now. Before it was some other city I don’t remember, I emailed Shopify to be removed from their spyware and it happened for a few months and now it started again. These are companies that spy on your website to determine your best sellers and sell the info to who will buy it. It’s shameful I agree but as far as I know it is not illegal.
It seems there is nothing to worry about, it appears to be Google's data centre. I checked the IP another reply had posted. I have had the same visits for a few months, very frustrating, I even blocked Iowa with an app and the hits kept coming. Shopify chat told me a month ago it was probably Google, and indeed that is what it appears to be.
I have done some testing and found this is caused by Shopify's new Site Speed Report feature. I have written more about it in the post here;
Make sure you contact Shopify Support and get them to change the feature if it is affecting you.
