Maybe you have automated your Spybot.
Open Spybot in the advanced mode via the menu item mode, go to ‘tools’->’System Startup’
Then mark the following entry and remove it: C:\Program Files\Spybot – Search & Destroy\SpybotSD.exe” /autocheck
If this does not help maybe this is due to the message during the scan “It is recommended that you reboot and scan again to find items that may be uncovered only after a reboot.”
If you need to you can download the latest version of Spybot S&D from our website and also download a new advcheck.dll file.
Move those two files: SpybotSD.exe and advcheck.dll to your program installation folder, and accept to replace the old ones.
