The most common mistake made when talking about a computer virus is referring to a worm or Trojan as a “virus.” The terms Trojan, worm and virus are often used interchangeably, but they do not refer to the same thing. Viruses, worms and Trojans are malicious programs that can damage computers and they are completely different and each of these has its difference.

Differences of the Virus, worm and Trojan

What is a computer worm?

The computer worm is another of the most common types of malware on the network, and its main difference from computer viruses is that it does not require user intervention or modification of any existing file to infect a computer. For the rest, it has the characteristic of replicating itself to spread over the networks to which a device is connected.

When it manages to penetrate a computer, the worm tries to obtain the addresses of other computers through your contact lists in order to send them copies and try to infect them as well.

What is a Trojan virus

The Trojan virus arises if we download an apparently normal program, but then it turns out to do a double function that we ignore. This program is the back door that makes our computer vulnerable to other attacks. It is not necessarily a destructive program in itself, but if they have put it into us, it is because they do not have good intentions.

There are many varieties, but the fundamental difference of this virus is that the Trojan does not replicate itself. In other words, it carries out specific actions to control the security of our computer. But the danger is greater serious that it is very difficult to detect.

What is a computer virus

A computer virus is a type of malware whose objective is to alter the correct functioning of a device. It does this by infecting the files on a computer using malicious code, and its main characteristic is that it requires user intervention to be executed.
