Hjlhef68Cb0 just downloaded to my Galaxy S4. What is it?

[AC Question]

And now it's asking if I want to replace the existing Hjlhef68Cb0. What is this file? Nothing found on internet.

Welcome to Android Central! Is this an actual app, or is it just some file that was downloaded? It sure sounds suspicious. Check your App Manager and see if there's an app by that name that's showing as installed.
