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.
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.
