Solved: All components of Avira won't uninstall, W7 64 bit Two components uninstalled what seemed well: "Avira update" and I think it was "Avira Security" or something. Avira OrganiZer uninstalled dirty: disappeared from installed programs list, but it did leave a small window which stayed minimized, could not be brought front with Task Manager either, and I had to finally reboot the computer.
