Can you provide the files that Wordfence has flagged as modified? You can copy-paste the code into pastebin.com and we can compare it to the original files for the Minimal Coming Soon plugin.
In most cases, the changes were simply the plugin being updated, but it might also be a malicious change.

There are several video tutorials out there that may be more helpful than me writing text instructions. I’ve skimmed this one, and it looks pretty informative. Please check it out and let me know if it helps.
