Do you need to pay for antivirus?

Windows

Microsoft Defender (in Windows Security) is built in, free, and scores well in independent tests. Make sure it's on: Start → Windows Security → Virus & threat protection.

Mac

macOS has built-in protection too. Stick to the App Store and trusted developers.

When a paid product can make sense

• You want extras like a password manager, VPN or identity monitoring in one bundle
• You run a small business and want central management

What actually protects you

1. Install updates for your operating system, browser and apps
2. Use a password manager and unique passwords
3. Turn on two-factor authentication
4. Be careful with links and attachments
5. Keep backups, so ransomware can't hold you hostage

Avoid

Pop-ups selling "PC cleaners" or "virus removal." And don't run two antivirus programs at once: they fight each other and slow everything down.
