Do I still need antivirus software?

Short answer

Modern Windows, macOS, Android and iOS include built-in malware protection that is enough for most home users when combined with automatic updates and careful downloading. Extra antivirus can help in some cases, but it does not replace updates, backups and MFA.

The details

Microsoft Defender is built into Windows, and Google Play Protect is built into Android. Businesses usually need more: endpoint detection and response (EDR) tools that record activity and help investigate incidents across many devices.

Terms explained

EDR (endpoint detection and response)
Endpoint detection and response (EDR) software records activity on laptops and servers, detects suspicious behavior and lets responders investigate and contain threats remotely.
Malware
Malware is any software designed to harm, spy on or gain unauthorized control of a device, network or account.
Multi-factor authentication
Multi-factor authentication (MFA) requires two or more kinds of proof to sign in, such as a password plus an app prompt, security key or biometric unlock of a passkey.
