hmmmm, how about the actual user takes responsibility for there actions, according to the article this trojan like many requires the user to download and run an exe (executable) file. I can see not placing blame on a few beginners that do not have a mentor to show them the way.

if you let your parrent or children on the net and you do know better shame on you, if a few families slip through the cracks of education on the bad element of the internet and I get spam or trojan invatation from them I offer help. If they refuse and I get another further content and messages from them if I do not wish to remove them from contact list is delayed or deleted as I know I can not trust them to do the right thing.

While I do hold MS accountable for releasing such a bad operating system, it is also just as much blame for an end user to continue using it.

Just like when you was a kid, when your mother told you if you hand out with them bad apples you might get blames for something you did not do, just the way it is. So keep hanging out with the likes of Microsoft and see what else they get you blamed for.
