Ok, so here's the deal....I ran REvo again, and it found a bunch more Avast stuff...so I deleted everything, rebooted, did it again. It found more stuff again...deleted, rebooted again...did it again, and it didn't find anything. Rebooted, did it again, didn't find anything. Rebooted. Installed Avast (I accidentally used the online installer instead of the full installer) BUT it worked...installed in about 2 minutes. Inserted the license file without an issue. Rebooted again...took quite a bit longer to reboot this time, but it finally did and I think we are in business!
From what I can tell - the update installer failed a few days ago and for some reason, there were two instances of the software - one being the main instance and one being a reference for the updates or something? I'm not really sure -either way - the update failed....but after all this it is working now
