FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A worm is similar to a virus by its design, and is considered to be a sub-class of a virus. Worms spread from computer to computer, but unlike a virus, it has the capability to travel without any help from a person.

Detailed explanation-2: -Once a worm has entered your system, usually via a network connection or as a downloaded file, it can then run, self-replicate and propagate without a triggering event. A worm makes multiple copies of itself which then spread across the network or through an internet connection.

Detailed explanation-3: -While some computer worms require user action to initially propagate, such as clicking on a link, others can easily spread without user interaction. All that’s necessary is for the computer worm to become active on an infected system.

Detailed explanation-4: -Worms are mainly spread in small bits of poo from people with a worm infection. Some are caught from food. You can get infected by: touching objects or surfaces with worm eggs on them if someone with worms doesn’t wash their hands.

Detailed explanation-5: -Though viruses typically require people to trigger an executable file which contains the virus, worms don’t require human interaction. Attackers actually program worm malware to make copies of themselves, spread those copies, and remain active on an infected system.
