4. BASIC MALICIOUS CODE TERMS • VIRUS — a virus requires that you take an action before it can infect your computer, such as opening an infected e-mail, or clicking on particular link • WORMS — a worm doesn’t have to be responded to to infect your computer. They feed off of software weaknesses and vulnerability. After the worm is inside the software, it searches for other computers to infect. Worms operate through e-mail and web pages as well • TROJAN HORSES — a trojan horses is software that is disguised as something else. Because of the disguise, users allow them onto the software without knowing that harm is being done.
