Do you still need antivirus in 2026?
Windows Defender (built into Windows 10/11) is significantly better than it was 5 years ago and handles most basic threats. However, dedicated antivirus still adds meaningful protection for:
- Ransomware protection — dedicated behavioral analysis catches new variants faster
- Phishing and web protection — blocks malicious sites before they load
- Identity theft monitoring — alerts when your personal info appears in data breaches
- VPN — encrypted browsing on public networks
- Performance — some suites include cleanup and optimization tools
For power users who are careful with downloads, Windows Defender may be sufficient. For everyone else, the added protection is worth the cost.
