Hello,
Which version of Spybot-S&D are you running, open Spybot Search & Destroy > Help > About. There you will find version and date of last definitions.
Also, did you try running a Spybot-S&D scan in safe mode which allows the program to try and remove items that keep reappearing after a scan, despite having been 'fixed'.
Reboot your computer into SafeMode by doing the following:
* Restart your computer
* After hearing your computer beep once during startup, but before the Windows icon appears, begin tapping F8.
* Instead of Windows loading as normal, a menu should appear.
* Select the first option, to run Windows in Safe Mode.
Open Spybot-S&D while still in safe mode.
* Close all browsers, check for problems and fix everything found in red
* Repeat until no more items are found in red
* Close Spybot-S&D
* Reboot back into Windows
