Answer 1

Computer worms are similar to viruses in that they replicate functional copies of themselves and can cause the same type of damage. In contrast to viruses, which require the spreading of an infected host file, worms are standalone software and do not require a host program or human help to propagate.

The basic difference between a Trojan and worm is in their functionality. Trojan horse is: An imposter that claims to be something affordable but actually is malicious. The main difference between virus and Trojan horse is that the former can’t replicate itself. Trojan virus comprises of malicious codes that when it is triggered it often result in theft or loss of data. Trojan horse spreads only when one invites this program onto a system. It can spread instantly if you download running files from internet or open email attachment.

Worm on the other hand is: A kind of program that can easily replicate itself easily from one system to another without any aid of a host file. This is a sharp contrast to the feature of virus as it needs an infected swarm file to spread properly. Often worms exist within other files. Usually worm discharge document that already has worm macro inside it.



Trojan horses are impostors--files that claim to be something desirable but, in fact, are malicious. A very important distinction from true viruses is that they do not replicate themselves, as virusesdo. Trojans contain malicious code, that, when triggered, cause loss, or even theft, of data
