Railworks.exe is contantly deemed a threat by AVG.  WHY, this is the executable for starting Dovetail Games Train Simulator 2017.  I have REPEATEDLY told AVG to correct this over a few years, and NOTHING has been done!   Now, Train Simulator will not start, and I believe that AVG has corrupted the file.  I am VERY annoyed at this, and will be looking for another reliable virus checker like Kaspasky.
I HAVE HAD ENOUGH OF THIS!
