Digital Trends - A new study from Internet security giant Symantec shows cybercrime affects everyone everywhere, and US Internet users are particularly vulnerable. Almost three-quarters of US Internet users are cybercrime victims, and the US ranks third on the list of countries attacked the most. When looked at globally, the number is still eye-opening, affecting about two-thirds of Internet users. Cybercrime includes computer viruses, online credit card fraud, and identity theft.
