I'm already in the middle of trying to clean my PC from the frakking redirect5 virus, and now my laptop is stuck. It says 'Please do not power off or unplug your machine. Installing update 2 of 31.' The cursor is spinning as though it is thinking but it has been stuck like that for about 5 hours. There is no response to any keys including ctrl + alt+ delete and if I hold down the power button to turn it off it just goes back to the same screen when I turn it back on again. Please help soon, i am now without 2 computers! I think im starting to get withdrawal symptoms! Thanks!
