Surfing the Web
Just by browsing the Internet, children can come across websites with images, video and content that contain pornography, violence, racism, and other harmful information.  A lot of times children will come across inappropriate content without even trying.  Pop up adds that look appealing to children may lead them to harmful websites.  Simple misspellings in searches can also lead them to these sites.  It is very easy to access this sort of information.

Strategies
Talk to your Internet Service Provider about kid safe options.  There are kid friendly search engines and kid friendly websites that help create a safe online experience for children.

Install filtering or blocking software on your computer that will help block unwanted content from appearing on the computer.  It is important to note that while filtering software does block access to inappropriate sites, it is not 100% effective.

Talk to your children about what to do when they are exposed to inappropriate content.  Encourage them to talk to you and let an adult know immediately when it appears on the computer.

Talk to your children about not clicking on pop up ads when they appear, especially if they contain harmful content.
