SRV 90 answered your Mac question. And I know what a struggle it is with making sure the kids don't visit virus prone sites. I had to bug my kids about it for years. The bottom line is she went to some site or opened some sort of an attachment that let that flea get through if you have adequate virus protection. If you do have a good virus program to pick up a flea means she let it through, otherwise if she was just surfing and came across a flea her firewall would have slammed down and issued a warning. It can be a real struggle to teach kids how to navigate the web safely.
