My children tend to use the computer fairly often. When they were younger, they used it occasionally. But, now that they're older, they use it almost all the time. They use it to research projects for school. They use it to communicate with their friends. They use it to purchase books, movies, games and almost anything else. But, are there computer security issues with which I should be concerned? From things I've seen on TV and stories I've heard about, whether truth or not, I wonder about whether they're safe using the Internet as much as they do. I need to find the best ways to protect my children.
