- Ransomware: Ransomware is a type of malware that encrypts your files and demands a ransom in exchange for the decryption key.
- Trojans: A Trojan is a type of malware that disguises itself as a legitimate program but actually allows unauthorized access to your device.
- Adware: Adware is a type of malware that displays unwanted advertisements on your device, often redirecting you to malicious websites.
