Simple Computer question re: viruses, trojan horses and worms |
|
Can someone give me a simple definition of the difference between these? I can't seem to grasp the difference between a trojan horse and worm in particular.
Thanks for your response

A Trojan Horse is a program usuaully sent by an e-mail attachment that opens ports on your computer so it's vunerable to attack.
A worm is basically the same, only it exploits weaknesses in an operating system (like XP) to open one or two specific ports.

that helps. So, a trojan horse will probably be let in through an email attachment. How is it different from a regular old everyday virus?

Is a program that will basically trash your computer.
A hacker scripts a trojan or a worm so he can use your computer for his purposes like a denial of service attack.

gets into your computer disguised as something else. And does damage. It doesn't necessarily replicate.
A worm is self replicating. Theoretically a trojan can be a worm.

4. there is no [longer a] difference |

In state-of-the-art Software Engineering publications all of those are "trojan horses". One might construct a (historic) difference: a "worm" uses a security issue to invade and replicate itself; a "trojan horse" is introduced into the system disguised as something else, a programm doing more than it should do (for example offering access to outsiders). However many worms are/include trojan horses and vice-versa - so a "trojan horse" is a program doing something not specified. Many many applications fall under this definition.
