It is being detecting as a potentially unwanted program or PUP, not a virus. ByteFence is a rebrand of Reason Core Security, with a different UI. Unlike Reason it is only available as a paid product. Several scanners detect ByteFence as a PUP because it sometimes come bundled as an unwanted extra with other software.
If you contact ESET they should be able to remove the false positive, so that they continue to detect ByteFence, but no longer detect Reason.
