Re: Not surprising...
Even assuming that people actually learnt something in the weekend course you propose, all you do is raise the bar slightly. This may stop some random passer by from using your network to find out what time the next bus is but it won't stop anyone with truly nefarious intentions and now , in their eyes, its the governments fault they've been hacked because they did everything they'd been told in class.
I'm not saying that education isn't a good thing, it clearly is. You're not going to teach people, who don't want to learn, all about internet security in a weekend though.
Further to this, sooner or later, the majority of people will secure there network anyway either because they've been hacked or they know somebody who has.
It'll make bugger all difference though. Everyone has locks on their doors these days but people still get burgled.
As for your anti virus suggestion, do you work for McAfee ?
