Update
I don’t think Adobe Reader 11 is available for Windows Vista - that’s why the links kept taking me to 10. I discovered this after following a manual download link that was left in response to someone’s inquiry on the Adobe forums. As soon as I select Vista as my ‘Operating System,’ Adobe Reader 11 is no longer an option, only 9 and 10 are available. I use Reader once in a blue moon so hopefully it’s okay to stick with the latest version of 10…and keep checking for updates.

Since reinstalling version of 10, and restating the computer, I’m no longer seeing any unscannable files in the Avast! scan - so that’s at least bit of good news. :slight_smile:

A huge Thank You to everyone who helped me out and answered all my wonky questions. Avast! forums truly is one of the kindest/most helpful. xo
