Microsoft Defender ships with Windows 10 and 11 and consistently scores near-perfect in AV-Test and SE Labs evaluations. It updates automatically, needs no account, and covers ransomware protection and firewall basics.
Bitdefender's free antivirus provides real-time threat protection with a minimal footprint and consistently excellent detection rates in independent testing.
Avast Free includes antivirus, Wi-Fi security scanning, a password manager, and browser protections in one free package. Opt out of data sharing during setup to keep it privacy-friendly.
Malwarebytes' free version is the standard on-demand scanner for removing malware, adware, and PUPs that other antivirus tools miss. Run it alongside Defender for defense in depth.
