Windows Defender really hates Paradigm Light Designer Uninstaller v1.2.2

It seems that windows defender (win10) is really really convinced that  C:\Program Files (x86)\ETC\Paradigm\Light Designer\uninstall.exe contains Ransom:Win32/Genasom. 

I believe it is only LD version 1.2.2. that is being flagged

Every few days I have to restore the "Removed Threat" that is 1.2.2's uninstaller, and re-white list it.

I am not sure if there is anything that can be done, being a very very old version (that I needed to install a few weeks ago for an old job), but if anyone has any pointers....this is getting rather annoying.
