Ransomware is a type of malware that encrypts your files and demands payment — typically in cryptocurrency — for the decryption key. Attacks surged 78% in 2025, affecting individuals, businesses, and healthcare providers alike.
The most effective protection combines three layers: a quality antivirus with dedicated ransomware shields (Norton, Bitdefender, and Malwarebytes all perform well here), a disciplined backup strategy using the 3-2-1 rule (3 copies, 2 different media, 1 offsite), and basic security hygiene such as keeping software updated and being cautious with email attachments.
Never pay the ransom. Payment does not guarantee recovery, funds criminal enterprises, and marks you as a payer — making you a target for repeat attacks.
For most home users, enabling the ransomware protection feature in your antivirus suite, combined with regular cloud backups, provides adequate protection against the vast majority of ransomware variants.
