I analyzed gravity forms files with various programs installed on my win10 64bit computer, and they confirmed that there’s no malware. Also, I submitted file to another online virus checker and you can see the result:
https://virusscan.jotti.org/en-US/filescanjob/wnrm1x1jam – nothing found.
You could never be too careful, but virus total is known to report a false positive even on simple text files, and I think that this is the case.
So, no malware here :-)
