I installed Spybot 2.0 beta 3 on my mom's computer last night to give it a try. The scan ran faster than Spybot 1.6.2, which is currently installed, but after a system reboot, the Spybot 2 cleaner started automatically and stopped responding to the system. So, I uninstalled it for the time being and will try it again later.

After uninstalling it, I ran "CCleaner" to look at the registry and found some things left behind by the Spybot uninstaller.

Attached is a screenshot.

Peace...
