The computer is frozen. A program is not responding

Push the Ctrl, Alt, and Delete keys at the same time. Then, start the Task Manager, highlight
the program’s name, and hit the End Task button.
 Perform a hard reboot by simply pressing the on/off button to turn off the computer
manually. This action should only be done as a last resort if you have an unresponsive
program or critical error. This process could cause data loss or corruption.
 Once the computer is responding again, run a virus check.
