Do you need antivirus software on Windows in 2026?
SOFTWAREWindows includes Microsoft Defender, which is turned on by default and is a capable protection for most home users.
When the built-in protection is enough
- You keep Windows updated
- You download software only from official sites
- You do not open unknown email attachments
When to consider more
Families with children, small offices or people who often handle files from unknown sources may want extra features like parental controls or central management. Avoid free tools that bundle toolbars or ask for payment through pop-ups.
Check it is on: open Windows Security, then Virus and threat protection. Green ticks mean Defender is active and up to date. If you see another antivirus listed, make sure only one is running.
