Did you tried to boot computer in Safe Mode ?
If you want to boot in Safe Mode, do the next:
1. Restart the computer.
2. After hearing your computer beep once during startup, but before the Windows icon appears, begin tapping F8.
3. Instead of Windows loading as normal, a menu should appear. Select the first option, to run Windows in Safe Mode.
4. Open Spybot S&D while still in safe mode.
5. Close all browsers, check for problems and fix everything found in red.
6. Repeat until no more items are found in red.
7. Close Spybot-S&D.
8. Reboot back into Windows.
If that doesn't work, then:
