Honey and the kids wonder why they are not allowed to touch my computer... Of course no one did anything!

On their computer they have "Internet Security 2010". It looks like the sole purpose of this software is to get you to buy the unlocked version of the software. A search shows it as a hoax / virus. Has anyone else encountered this and how did you get rid of it.

I am currently running an AVG scan of the system, hoping it will find it.
