Most unsigned exe files SHOULD trigger things like windows defender. It typically costs money to get an exe digitally signed, or time to submit your exe to microsoft for review. My little game jam game definitely didn't warrant either of those routes - I probably should have tried to package for browser with love.js but alas. Here is a quick little thread I found on the love forums about it so that you don't have to take my word for it:

In any case, I appreciate you trying to give it a look. Thanks!
