Here is the link to the Avast web page that I got by way of going to the links within my Avast program:
The one that hit me is:
I took Avast off two of my macines and was ready to take it off this computer in the basement and then it hit. I did a WRA scan after that and it came up clean. Would WRA have found it if Avast didn't? Now I am wondering it I shuold continue to run both programs on all machines.

The reason Avast will have got to it first is that if you have another antivirus program on your computer, WSA is smart enough to know that the other antivirus program is a good program just trying to do its job for you. So rather than trying to argue with that program and trump it, it will just let it work for you. Webroot was still there for you if it was needed.
