gpg4win-3.1.13.exe on Virustotal two engines detected this file

gpg4win-3.1.13.exe - on two Virustotal engines has detected this file
The version 3-1-13 verified on virustotal showed two positives:

Hello Marco,
don’t worry, be happy. Only two out of 60 engines detected the file as suspicious. That is an acceptable quota for a false positive. Also the detections announced different types of malware. On the other hand: those engines are not considered to be the most reliable ones. In case an alarm would be generated by ESET, Sophos and Kaspersky labelling the same malware type, I would be worried.
Another good proof for the correct and undamaged download is the signature file.
