IDP Generic Threat blocking my software instal

I am getting a threat about IDP Generic.  At first it said my Sage software that I have had installed forever was infected with IDP Generic.  Then I uninstalled and reinstalled and then it told me that that the set up file is infected with IDP Generic.  And then won't let me reinstall it.  Even if I do an exception.

Any ideas.  I have to have that software installed.
