I ran it through my own antivirus and it found no threats. Game Maker Studio executables are known to trigger false positives with some AVs due to the technique they use to decompile data. I don't visit obscure sites or download files all that often, and I run AdwCleaner fairly often, so it's probably nothing.
EDIT: Either way though, if you still aren't comfortable (or your PC plain old won't let you run the file,) I've also added an NSIS installer version. It's a slightly larger file, but they tend to be a bit less problematic.
