A computer virus attaches itself to a program or file so it can spread from one computer to another

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. A worm takes advantage of file or information transport features on your system, which allows it to travel unaided. The biggest danger with a worm is its capability to replicate itself on your system, so rather than your computer sending out a single worm, it could send out hundreds or thousands of copies of itself, creating a huge devastating effect.

Answer 2

A computer worm is a self-replicating computer program, similar to a computer virus. A virus attaches itself to, and becomes part of, another executable program; however, a worm is self-contained and does not need to be part of another program to propagate itself. They are often designed to exploit the file transmission capabilities found on many computers.

and In computer security technology, a virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents (for a complete definition: see below). Thus, a computer virus behaves in a way similar to a biological virus, which spreads by inserting itself into living cells. Extending the analogy, the insertion of the virus into a program is termed infection, and the infected file (or executable code that is not part of a file) is called a host. ...

Answer 3

a working laptop or notebook malicious application is a self-replicating notebook application resembling a working laptop or malicious application. a virulent disease attaches itself to, and turns into component of, yet another executable application; whether, a working laptop or malicious application is self-contained and does not might desire to hitch yet another application to propagate itself. they are regularly designed to make the main the report transmission applications discovered on many computers. the important distinction between a working laptop or malicious application and a working laptop or malicious application is that a virulent disease can not propagate by capacity of itself while worms can. A malicious application makes use of a community to deliver copies of itself to different structures and it does so with none intervention. often, worms injury the community and consume bandwidth, while viruses infect or corrupt archives on a concentrated notebook. Viruses in many situations do no longer impression community overall performance, as their malicious events are often restrained interior the objective notebook itself.

Answer 4

A worm is a small piece of code, all it does is spread itself and reproduce. So it'll try to get itself sent to all your e-mail contacts. Once its on your machine, every key that you press will cause it to double. So you have one, then 2, then 4, then8 and so on until your hard drive is full of the code and your machine locks up.
A virus is a piece of code that has a malicious instruction designed to cause specific damage to your machine by interfering with software.

Answer 5

well a worm works its way thru your sys and a virus stays in a file untill u access it and this action releases it into the computer

Answer 6

The difference is they both damage differnt things in the computer like one frezzes it and the other just like dletes all your info and stuff like that.
