UPDATE: Looks like the 2.6.0a release on codeplex is now being flagged by Chrome as malicious. I don't know if it's the file or codeplex.com that is the issue (our older releases with thousands of downloads appear to now be falgged as "malicious" too now). So I have also made the setup file available as a release from our github repo too - https://github.com/DaxStudio/DaxStudio/releases/download/2.6.0/DaxStudio_2_6_0a_setup.exe
If you had trouble dowloading the 2.6.0 release yesterday there is now a new 2.6.0a release up at https://daxstudio.codeplex.com/releases
Yesterday's release of DAX Studio 2.6.0 started off OK. We've had over 400 downloads, but then at some point the browsers seem to think the installer was a malicious file. We're not sure why, but all of them have started throwing up warnings, Chrome seems to be the worst offender, saying that the file is malicious and only giving you the option to discard it
And both Firefox and Edge give you very scary warning, but will let you download the file.
The advice on the Chrome "learn more" link is very generic and there does not appear to be any way of submitting for a re-assessment of this judgement.
I checked both the original file and then downloaded the file from codeplex and checked again (just in case something had infected the file after it was uploaded to codeplex) using Googles virustotal.com site and both times 0 out of 55 antivirus scanners reported any issues.
If you are curious below is a link to the VirusTotal.com results showing the detailed results:
