Installation of HYSPLIT_win64U_v4.2.0.exe failed

Post by filioglo »


I have tried to install the latest unregistered Hysplit version and the installation fails every time as my antivirus program detects a trojan.
The trojan name is TR/ATRAPS/Gen.
Is it something that I should check on my laptop or indeed the file is corrupted?

Thank you for your time,

Thank you for informing us of your installation issue. This happened several times in the past few years and our IT believes it is a false positive. Here is why.

In February 2019, in response to a "TR/ATRAPS GEN2 Trojan" report, our hysplit Windows distribution was scanning using 66 antivirus engines. Five of them flagged it but the virus names they reported were all different. This led us to believe the detection was a false positive.

Below are MD5 checksums that could used to check the integrity of your downloads:
