FreeFileSync

I am in need for a good File synchronizer, and FreeFileSync seems the best option there now. I have researched around and there seems no major issue except with Norton. Their site, freefilesync.org FAQ has the following: "Some anti-virus programs, most notably Norton by Symantec may falsely flag the installer as dangerous and delete it without providing further info. This is because Norton uses a so-called "reputation-based heuristic", which will simply delete all files that are not well known or commonly downloaded."

The latest Norton forum discussion was from 2013. What is the latest on this? Given FreeFileSync has been around at least a decade, has Norton finally acknowledged it as Ok? What is the recommendation to install?  Thank you in advance.
