What can I do if Spybot-S&D is running forever, never stopping the scan?FAQ #017
With the installation of 1.1 rel 4, there was a very small chance that all automation options have been enabled during the installation. This would cause a loop that would restart the scan again and again. If you experience such problems, please switch to the "Settings" page in Spybot-S&D (the page with the treeview), and disable all settings in the category "Automation".
