why you posted this without being investigated?

Excuse me, I think this is a translation error, but why should I be investigated for answering a question in a public forum? 

Edit:

I think you're asking if I investigated the executable?

If that's what you mean, no, I don't investigate executables. It requires having certain applications installed and running the program in a controlled environment, and I don't have those tools installed.

The link you posted leads to a blog page, and that page has an external link. The associated account has no games created, and that alone is a major red flag. No one who cares about their computer's security should download and run the application from that link. It's a basic security concept: if something seems suspicious, don't hesitate to treat it as malicious unless you can prove otherwise.

Itch is infested with malware. The criminals try every day in a lot of ways. Posting blogs with links to malware is one of the many things that are done and for that Itch has no satisfying solution to prevent it.

Those blogs are especially nasty, since they appear in google search and you cannot report them directly.

(I think it's having investigated. Not being investigated ;-)
