When I go to the Avast control panel and click on update for the program, it says that 2014.9.0.2013 is available. That is what I upgraded to yesterday only to have my browser windows corrupted. I went backwards to the set point, leaving me at 2014.9.0.2008.

Your link takes me to the discussion of 9.0.2013 which, I thought, I had already tried. Are there intermediate upgrades between .2008 and .2013 that I should have done first?
