Hi, did the repair, and it did not seem to make any difference. According to the avast window, streaming updates are enabled and connection is established. Last update: 9/18/2013 2:15:30 PM. The only thing I can think of is that the streaming updates for this particular version, 130326-1, have ended. I take 130326-1 as a base file. Maybe I need to get a new one? If I get a new one (how?), will that get rid of the current crop of six months worth of stream files, assuming they're not needed? There are hundreds, if not thousands, of little stream files.
