Boot into safe mode.
open the task manager by pressing the control, alt, and delete keys together.
Select the processes tab and click on the entry SMCSS.EXE if there, and click on the end process button, followed by yes. Now close the task manager.
Run Hijackthis, and let hijackthis fix the following by putting a tick in the little box next to, if still there.
