We compared protection scores, performance impact, extra security tools, and pricing. Our pick: Bitdefender for the best overall balance of strong protection, low system impact, and useful extras.

Best overall protection

Why we prefer Bitdefender

  • Excellent malware and ransomware protection with multi-layer security.
  • Light on system resources so your PC and laptop stay fast.
  • Strong extras: web protection, safe banking browser, VPN, password manager (on certain plans).
  • Clean, modern apps for Windows, macOS, Android, and iOS.
Heads-up: Want very granular configuration and a long track record in lab tests? Kaspersky is a solid option. Prefer a big-brand bundle with identity and device coverage? McAfee leans into “all-in-one” protection for multiple devices.
