Can you please do the following.
===============
You will have to disable Spybot's Teatimer before we begin, as it will interfere with the fix. To do this can you start Spybot and go to the Mode button and select Advanced. Go to Tools > Resident and uncheck the box next to Tea-Timer. Make sure that the icon in the system tray is no longer there. If it is, just right click on it and select "Exit".
Download ResetTeaTimer.bat.
Double click ResetTeaTimer.bat to remove all entries set by TeaTimer.
Do not forget to re-enable teatimer when we are done :).
If teatimer gives you a warning afterwards that some changes were made, allow this instead of blocking it.
===============
Scan with HijackThis and then place a check next to all the following, if present:
