mach4 industrial 5596 x64 is detected by Microsoft defender as being a virus. I hope it's a false positive. I had to turn off real time protection to install

M$ real time virus protection gives a false positive on pretty much all software with copy protection in it.  BTW, there are not any 64 bit motion plugins yet.    That version is out there for the plugin developers to make 64 bit plugins.
