Yes, AV software, especially HitmanPro are not gospel. 67 other AVs came out clean. But let’s say for the sake of argument that they’re all wrong.
“Trojan-Downloader” is a class of Trojan that downloads a payload. Which means they need to use a socket somehow. $ sha256sum.exe ghc-8.2.2/lib/bin/touchy.exe 5ffdaa7da4381637ab2a0ec327118cd933398a477430e2f5d94e9d53c53f2782 *ghc-8.2.2/lib/bin/touchy.exe Is the binary I’m looking it, it matches the hash on the total virus link and yours. This is the source of touchy https://github.com/ghc/ghc/blob/ghc-8.2/utils/touchy/touchy.c The application does not import Winsock, so networking seems more unlikely, but it imports GetProcAddress, so let’s say for the sake of argument it’s Dynamically binding to the socket library. http://lpaste.net/3408264924009332736 is the full string table. Which contains no ascii string starting with “WSA”. So unlikely since you need to name the function you want to call, and you need to initialize the sockets, so WSA. This is the full disassembly of touchy.exe http://lpaste.net/7667888088021991424 Below you’ll find an inline copy of main, it pretty much follows the source in touchy.c. I’m pretty confident that HitmanPro is just throwing a false positive, I won’t be going through the CRT startup code.

That said, I still have the 2 builds yield different results from Hitman Pro on the clean boxes. And Bitdefender, on my machine, (albeit being obtuse) chucks a fit over it. It doesn't detect the EXE files; but detects secondary consequences of them running. I really think something is afoot here.

New Haskell install was tripping my Bitdefender like crazy and in weird ways - not new as that's how bitdefender rolls. However, I retested in a clean test, with (free) Hitman Pro I started from a base case with 2 clean windows 8 VMs. New 8.2.2 install - has virus Old 8.0.2 Jan 2017 - no virus According to Hitman Pro, touchy.exe, haddock-8.2.2, ghc-8.2.2.exe, and unlit.exe have some problem post-install. I went no further on the VMs. "Detection Names Kaspersky Trojan-Downloader.Win32.Paph.fsv " Bitdefender didn't get it on install but would lock the whole thing down on the first run of "Cabal". _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs _______________________________________________ ghc-devs mailing list ghc-devs@haskell.org http://mail.haskell.org/cgi-bin/mailman/listinfo/ghc-devs -- brandon s allbery kf8nh sine nomine associates allber...@gmail.com ballb...@sinenomine.net unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
