Ransomware is a type of malware that encrypts a victim's files. The attacker then demands a ransom from the victim to restore access to the data upon payment.

• Regularly back up your important data to an external drive or cloud storage.
• Do not open suspicious attachments or click on untrusted links.
• Use reputable security software and keep it updated.
• Never pay the ransom, as there's no guarantee you'll get your data back.
