Here is an older article that I read when it first came out two years ago. The message is still good. It talks about bad stuff appearing on a computer without anyone even trying to get it. As this poor teacher discovered, an innocent click on a website link opened up what the online community refers to as a "porn storm," an endless barrage of pornography pop-up windows that can't be stopped without shutting the machine down. Within 5 seconds, over 100 windows with pornography could be opened automatically. Scary.
