Fatal error?

i know this probably should go to C&G… but its a weird thing that need a random view…

i’m trying to fix my parent’s pc… ie got hacked and won’t work… i got firefox on it and it works but i want to fix the problem… i tried running adaware to clean up some stuff… but when it runs… this dialog pops up and shuts down the pc in 45 secs… no clue what it is…

any ideas… and any idea on how to restore ie… i know its somewhere… but my google skills are off and i’m to tired to search kirupa for the answer(even though i will look afeter this)
