Worms have become a real threat for computer users for the past few years.

An important distinction between computer viruses and worms is that viruses require an active host program or an already-infected and active operating system in order for viruses to run, cause damage and infect other executable files or documents, while worms are stand-alone malicious programs that can self-replicate and propagate via computer networks, without human help. Viruses are typically attached to an executable file or a word document.

People tend to play fast and loose with security terminology. However, it's important to get your malware classifications straight because knowing how various types of malware spread is vital to containing and removing them. This concise malware bestiary will help you get your malware terms right when you hang out with geeks.

Choose a Session. Data Security. Cindy Ng. Viruses and worms are often used interchangeably: there are a few key differences in how they work. Both viruses and worms are a type of malware : a worm is a type of virus. Computer viruses are named after human viruses that spread from person to person.

The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system. Worms do not require activation—or any human intervention—to execute or spread their code. Viruses are often attached or concealed in shared or downloaded files, both executable files—a program that runs script—and non-executable files such as a Word document or an image file. When the host file is accepted or loaded by a target system, the virus remains dormant until the infected host file is activated. Only after the host file is activated, can the virus run, executing malicious code and replicating to infect other files on your system.
