confirming theme and demo content are correct

Hi,
A client sent me a theme file/demo content here.
https://drive.google.com/file/d/1jSoDk6nF3QjHD-YQ7pDMVAAthAUDl0qj/view?usp=sharing

Are there any online systems that I can run the zip file through to make sure there are no security issues/malware?
