What are Worms and Trojan horses?


Worms and Trojan horses are two types of malicious software (malware) that can harm your computer or network. 

Worms are malware that can replicate themselves and travel from one computer to another without any human action. They can consume a lot of system resources, such as memory or bandwidth, and slow down or crash your computer or network.

Trojan horses are malware that pretend to be something else , such as a game, a utility, or an attachment. They trick users into downloading or opening them, and then perform malicious actions behind the scenes. They do not replicate themselves like worms or viruses, but they can open a backdoor for hackers to access your computer or network remotely.
