Classification of Malware

There are many different types of malware that can infect your computer or device. Some of the most common types include:

Viruses: A virus attaches itself to other programs and replicates itself. When an infected program is run, the virus spreads. Viruses can damage files, delete data and disrupt systems.

Worms: Like viruses, worms spread by replicating themselves. However, worms don't need to attach to files to spread - they can move from one computer to another on their own.

Trojan Horses: Trojans masquerade as legitimate programs but contain malicious code. Once installed, they can steal data, damage files or install other malware.

Spyware: Spyware collects information about a user's activities without their permission. It can track web browsing, keystrokes and other sensitive data.

Adware: Adware displays unwanted advertisements on a user's device. It often installs other malware and tracks user activity to show targeted ads.

Ransomware: Ransomware encrypts a user's files and demands payment to recover them. It is one of the most common and damaging types of malware.

Rootkits: Rootkits give attackers full control ("root" access) of an infected system. They can hide other malware and are difficult to detect.

Keyloggers: Keyloggers record a user's keystrokes to steal sensitive information like passwords and credit card numbers.

Cryptominers: Cryptominers use an infected device's resources to mine cryptocurrency for the attacker. They can significantly slow down the device's performance.
