Thanks for reporting it to them.
Your checksums match those from my original build, so I can confirm nothing has been compromised.
However, it's not really up to us to test random Windows anti-virus products, many of us do not even have Windows. Even a web service is cumbersome, when we'd have to upload lots of files, then help the AV makers fix their products. So, for issues like this, we'll need to rely on users like you to take action.
