if

  • CTRL ALT DEL or
  • the reset button or
  • pressing the power-button for 4 seconds doesn’t help:

pulling the plug persuades even the most stubborn PCs to shut down… ;D

afterwards:

  • try rebooting to last known good configuration or in SafeMode (F8-Boot)
  • if that doesn’t help: can you boot from XP-CD and see your data then ?

and give us more info about the virus location and system/Win-info :wink:
