Specific to Apple Store issue - sometimes one picks up a piece of Malware or Adware which if installed may interfere with connecting to the Apple Apps Store.

There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX  Foundation and Permission Limitation. 

The The Built in Security  is all that is required to protect the computer.

Should “ Certain & Specific Software “ referenced from above be installed - it will negatively impact macOS. It is suggested, to download directly from a respected ASC Contributor, the application Malwarebytes for Mac. 

It is free or paid for added features.

Run the Application and it should remove the malware / adware.

Once done, restart computer and test.

If you can't connect to the App Store, iTunes Store, or other ...
