text: help!!!! my computer keeps shutting down...? i have deleted cookies,files and history...but it keeps shutting down on me.  does any one know what might be wrong? try starting your computer in safe mode.  if this works then you almost certainly have a virus.  the best programs i have found for removing this type of virus is 'cwshredder', and 'hijack this'  if you need any more advice on these you can email me.
