If I re-scan the system with Hitman Pro, then the downloaded win64 setup file is being marked as malware, the bitcoin-qt.exe file, and bitcoind.exe file.
If I happen to scan with Avira, another anti virus software, then nothing happens. I downloaded it from bitcoin.org as always, and verified the signature ~ everything seems to be pointing at a false alert, but not 100% sure.
The previous (sub 0.15) versions were never resulting in whatever alert. Maybe that it has to do with important changes that a non technical person as me doesn't know anything about?
Edit ~ I downloaded a whole lot of setup files to test them, and it seems that almost every file of 0.13 and above triggers a malware alert. Everything below 0.13 comes out as clean. Maybe a SegWit related thingy?
But then again, some of the versions above 0.13 came out as clean too, and these have SegWit code as well.
