In the past, it was relatively easy to avoid getting viruses on your PC if you avoided visiting the Web sites that were known to cause them — often sites that had other illegal content on them. You could read your e-mail, do your social networking, catch up on some news, do your Christmas shopping and all of your other Internet tasks without really worrying that you were visiting a site that could potentially harm your computer. However, times have changed and so have the threats that lurk on the Web. Just being cautious and avoiding commonly known bad sites isn't enough — even innocent, trusted sites can unknowingly carry risks.
