Question

Tuition in malware both are affected by the system but how the trojan is different from malware

Answer 1

Malware:

This is a big catchall phrase that covers all sorts of software with nasty intent. Not buggy software, not programs you don’t like, but software which is specifically written with the intent to harm.

Trojan: 

Do you remember that story you had to read in high school about the big wooden horse that turned out to be full of guys with spears? This is the computer equivalent. You run a file that is supposed to be something fun or important, but it turns out that it’s neither fun nor important, and it’s now doing nasty things to your machine.

Answer 2

They differ in way of reacting on programs.
