Trojans may allow an attacker to access users' personal information such as banking information, passwords, or personal identity. Besides, Ransomware attacks are often carried out by using a Trojan.
A computer worm is a standalone malware computer program that replicates itself in order to spread to other computers. Often, it uses a computer network to spread itself, relying on security failures on the target computer to access it. Many worms that have been created are designed only to spread and do not attempt to change the systems they pass through. But they can cause major disruption by increasing network traffic and other unintended effects.
