A few days ago, my computer was infected with a few spyware. Even though I have clear them all out, my computer now cannot shut down properly. It used to be able to turn the power off by itself. Now it stops at the "It is now safe to turn off your computer" screen. It is the same when I select "restart the computer", it will stop at that screen without proceeding to restart the computer. Can anyone help me? Thanks so much.
