I’ve already looked into this before, and it seems that some antivirus programs will occassionally mark Unity games (or .exes) as viruses. I think its because your computer considers it an “unrecognized” file type. I scanned the uploaded files, as well as my computer, and they both appeared to be clean. That being said, if you aren’t comfortable downloading the file, then don’t do it! My apologies if this gave you a scare.
