Questionable Download and Install

I downloaded (and purchased) the latest update from ganttproject.biz., However my Antivirus trapped the install as suspicious. There have been problems with bad guys intercepting open-source software and replacing it with virus bearing versions.

The version was ganttproject-3.3.3316.exe and it has not been signed by your company. Is this a legit copy?

Hello,
You can check if the downloaded file is legit by calculating its MD5 hash and comparing it to the expected one (for this particular file, it must be 9505f15f583b155c52c6f50aa225e263).

The installer was checked by 62 antivirus tools on VirusTotal and they did not find any issues.
