Win32:SuspBehav-B [Heur]

I have been running program on my windows based computer for over 10 years with no problems.  I recently purchased a Mac and have been running the same program for several weeks now.  All of a sudden on March 11, 2021 I start receiving notifications that "Multiple threats secured!".  At one point there were as many as 251 files marked as threats.  It is my understanding that these are not threats, but just files that are need and have been used for the program since its beginning.  Is this something that will be fixed?  I really love my AVG products, but I do not want to loose access to this program either.

Hi Stormy, 

We will check this for you.
Could you share us the screenshot of the threat secured notification?
