Can't download from Avast or Comodo On Friday I finally got rid of my dialup and got Comcast high speed. Well, now my Avast won't update, and I also can't download updates from Comodo. I've had a little trouble also with other websites not connecting the first time I've tried them, but generally these others have worked after a second, third, or fourth attempt. Not so with the updating of these other two programs. Any ideas what may be causing this?
