Viruses are the most well-known type of malware. They are designed to replicate themselves and spread to other computers through infected files or programs. Once a virus infects a computer, it can cause a range of problems, such as deleting files, stealing information, and even damaging hardware components.
One of the most dangerous aspects of viruses is their ability to spread rapidly. They can infect other computers through email attachments, infected websites, or even through shared files on a network. To protect against viruses, it is important to keep your operating system and anti-virus software up-to-date, and to be cautious when opening email attachments or downloading files from the internet.
Trojan Horses
Trojan horses are a type of malware that are disguised as legitimate software. They are designed to trick the user into downloading and installing them, often by disguising themselves as a harmless program such as a game or utility tool. Once installed, the Trojan horse can steal personal information, log keystrokes, or open a backdoor for hackers to gain access to the computer.
To protect against Trojan horses, it is important to only download software from trusted sources, and to be cautious when installing new programs. Always read the fine print and be wary of any program that asks for personal information or access to your computer.

Ransomware
Ransomware is a type of malware that is designed to encrypt the user's files and demand a ransom in exchange for the decryption key. Ransomware can be incredibly damaging, as it can lock the user out of important files and data. It is often spread through email attachments, infected websites, or social engineering tactics.
To protect against ransomware, it is important to back up important files and data regularly, and to be cautious when opening email attachments or downloading files from the internet. It is also important to keep your operating system and anti-virus software up-to-date.
