I was innocently (honest!) browsing the vastness of the internet, when I came across an interesting page.
It displayed Windows XP like alerts, "Windows Security Alert" in all the colourful WinXP crayola themed glory and then proceeded to pop up another realistically rendered "window" which simulated a scan throughout my vulnerable Windows system. Yes, the windows were drag-able.

So if you are the so-called "Tech Support" for your family/relatives/friends (its a thankless job), you could save yourself alot of headache by educating your "users" about these threats. Change the default theme to something different. Install a net-nanny. Install a real Anti-Virus app (or two) which is updated frequently. Lock down the users' permissions. Boot read-only. Charge by the minute. Ban the user from computers.
Alternatively, you could get them to run Linux.
