Delphi applications considered 'dangerous' by Google Chrome

"Is there something harmful about my EXEs?"

No.

Here's a link to the results of Jotti's malware scan (which results with: 22 out of 22 scanners "found nothing"):

"Is there some way to make Google Chrome not block my EXEs?"

One option is to make it block nothing, evidently it's crap anyway. The option is in the "privacy" section in "advanced settings", here are the instructions:

Otherwise, you can check what google thinks about safety of your site:

The report seems to be somewhat indeterminate. Here's a quote (for rejbrand.se):

Has this site hosted malware?
Yes, this site has hosted malicious software over the past 90 days. It infected 0 domain(s), including .

Presumably you can also request a site review in the security issues of google webmaster tools. But apparently it's not always fruitful. That last link also suggests there's a way to send samples to google hoping that they would analyze better (AFAICT it's not part of webmaster tools), but this might not turn out to be practical depending on the number of executables/versions you produce.

I could reproduce this behavior with Chrome with your original EXE.

Is there some way to make Google Chrome not block my EXEs?

I can confirm that after I digitally signed it (with my company's signing code certificate) Google Chrome downloads this file without any issues. This is the most efficient (maybe the only) way to avoid this kind of problems.

Another quick solution is to pack the EXE with RAR. Chrome downloaded it with no problem.

Surely this is a False positive "detection" with Google Chrome. My Antivirus (NOD32) did not found any problem, and other browsers did not have any issues with your EXE.

NOTE also that Your domain might have issues (flagged) as @Sertac Mentioned. If I download your original EXE from my website the error message is %s is not comonly downloaded and could be dangerous. Same goes for any other EXE I uploaded to MY site. (You still have an option to "Keep" the file)

As welcome as the new features are, Chrome is in the unusual position of playing catch up to Internet Explorer 9, which features an arguably superior method of blocking potentially malicious downloads. Microsoft's SmartScreen Application Reputation rates downloads in three ways: whether they're digitally signed, the reputation of the author, and--arguably most importantly--how many times the file has been downloaded by others.
