This is an absolutely true story. A friend of mine called up a while ago, one who I always help with PC issues and he told me he "hadn't got enough Java", It made me laugh.
He's also had horrible things on his PC, hijacking google. A friend on MSN sent him a message saying the smileys were cool and because he knew the the person he happily installed them aghhh!
Every time I go round, I have to fix something despite trying to set him up to be more secure and trying to give him some basic do's and don't's, he has got better though.
oh and "don't remove the toolbars" (the ones reducing the size of the browser by a 1/3).
