Unlimited Extension zip file showing in Search results

So I purchased an unlimited extension then had to upload the plugin so that I can install it and every thing worked fine but later on I saw a very unusual thing.

When I was searching for pages in my search bar, the results page contained “PRIVATE: ALL-IN-ONE-WP-MIGRATION-UNLIMITED-EXTENSION.ZIP”. I don’t even know why or how its even doing that.

Not only that but in the description there seems to be a link to that download.

How do I not make this pop up in my search?? Why is it even doing this in the first place?
