Well I took the risk and installed Piplay 220.127.116.11 and it installed without any issue or virus warning.
I checked the setup.exe file with the Windows Defender before installing and it was clear so I went ahead.
It installed perfectly and as far as I can see, everything works really well.
I must say that so far I'm really impressed.
I don't understand why some people seem to have an infected install file when I downloaded mine from the MEGA site as usual. No virus.
