If CHROME marks Aurora as "Dangerous" or "Malicious" there is no need for concern. They are simply being overzealous about new downloads. The file downloads fine in Edge and Firefox. You can easily get around this issue by pressing CTRL+J and tell Chrome to keep the file. Feel free to check the valid digital certificate on Aurora.exe and Aurora.dll and also check it's status on VirusTotal where 3 of 60 AV's (no name brands) find it unsafe. Cheat Happens has been around for 20+ years and we didn't get here by distributing unsafe software.
