Git itself doesn't make any attempt to access those systems unless it's configured to do so (e.g. a remote is set up to talk to those systems and fetch or pull is used).

It's possible that you're using a distribution package that performs this behavior, say, to check for updates. I'd recommend that you contact the distributor, which in this case might be Git for Windows, and see if they can tell you more about what's going on. The URL for that project is at https://github.com/git-for-windows/git.
