My VM is running Avira. Deactivating it haven't impact on ssh-keygen. I still have > an Segmentation fault. Does the cygcheck, ldd, or strace still show ntmarta? If so, then it is likely the intercept might be installed and need uninstalled to deactivate! If you are running Avira Free, I get: https://www.avira.com/en/free-antivirus-windows "System Requirements Your device is not compatible Operating systems Microsoft Windows 7 Service Pack 1 or above with the newest updates, hotfixes, and service packs installed RAM 2 GB of RAM or more Disk Space Minimum 2 GB of free disk space (additional space for temporary and quarantine files needed) CPU type Intel Pentium 4 / AMD Athlon 64 Processor or faster (with support for the SSE2 instructions set) Browser: Internet Explorer 11 or newer Additional requirements To install, you’ll need administrator rights, an internet connection, and a web browser. For automatic antivirus updates and optimal malware detection, you’ll need an internet connection" So you should try that page from the system with issues, and try something else if you get the same response, as it appears that is pretty old code running, or just try something newer like MS Windows Security/Defender/etc. -- Take care.
