How we chose

  • Every tool on this list does the core job of antivirus software, so it can replace Bitdefender for most people.
  • We weighed pricing and free plans, ease of use, and the trade-offs you take on when switching.
  • Pricing comes from each vendor’s public pricing page and changes often, so confirm before you buy.

Buying guide: what to check before you switch

Antivirus software detects and removes malware, blocks dangerous sites and downloads, and often bundles extras such as a VPN or password manager. Windows already includes Microsoft Defender, so paid suites must justify their extras.

  • Independent lab test results
  • Impact on performance
  • Devices covered
  • Renewal price vs first-year price

Prices and features change often. Check each vendor’s website for current plans before you buy.
