Viruses
Viruses are computer programs that can duplicate themselves and spread to other files on a computer. They can corrupt or delete data, making a system unstable or even completely unusable.
Worms
Worms are programs similar to viruses, but they have the ability to spread automatically across computer networks, often by exploiting security vulnerabilities.
Trojan horses
Trojans are programs that pose as legitimate, but once installed, open a backdoor on a system, allowing hackers to remotely access the infected computer.
